These devices extend the advantages of solid tantalum technology to today’s surface mount circuit applications. Complementing multilayer ceramic chip convenience with capacitance ratings through 1500 µF, tantalum chip capacitors permit circuit designers to take full advantage of the benefits of surface mount technology. T491 Series — Industrial The leading choice in today’s surface mount designs is the KEMET T491 Series. This product meets or exceeds the requirements of EIA standard 535BAAC. The physical outline and dimensions of this series conform to this global standard. Five low profile case sizes are available in the T491 family. The R/2012-12, S/3216-12 and T/3528-12 case sizes have a maximum height of 1.2 mm. The U/6032-15 size has a maximum height of 1.5 mm, and the V/7343-20 has a maximum height of 2.0 mm. This product was designed specifically for today’s highly automated surface mount processes and equipment. This series uses the same proven solid tantalum KEMET technology acclaimed and respected throughout the world. Added to this is the latest in materials, processes and automation which result in a component unsurpassed worldwide in total performance and value. The standard terminations are 100% matte tin and provide excellent wetting characteristics and compatibility with today’s surface mount solder systems. Tin-Lead (SnPb) terminations are available upon request for any part number. Gold-plated terminations are also available for use with conductive epoxy attachment processes. The symmetrical terminations offer total compliancy to provide the thermal and mechanical stress relief required in today’s technology. Lead frame attachments to the tantalum pellet are made via a microprocessorcontrolled welding operation, and a high temperature silver epoxy adhesive system. Standard packaging of these devices is tape and reel in accordance with EIA 481-1. This system provides perfect compatibility with all tape-fed placement units. T492 Series — Military KEMET is approved to MIL-PRF-55365/8 (CWR11), Weibull failure rate “B” level or 0.1% failures per 1,000 hours, “C” level or 0.01% failures per 1,000 hours, and “D” level or 0.001% failures per 1,000 hours. This CWR11 product — designated as KEMET’s T492 Series — is a precision-molded device, with compliant leadframe terminations and indelible laser marking. This is the military version of the global IEC/EIA standard represented by KEMET’s T491 Series. Tape and reeling per EIA 481-1 is standard. T493 Series — Military - COTS The T493 series is designed for the COTS (Commercial-Off-The-Shelf) requirements of military/aerospace applications. This series is a surface mount tantalum product offering various leadframe surface finishes, Weibull grading and surge current testing options. The full part number includes a code defining the terminations, the Weibull reliability, surge test conditions, and the ESR range. The possible terminations include gold plated, hot solder dipped, solder plated, and solder fused. Reliability grading of B level (0.1%/kHours) and C level (0.01%/kHours) are available. Surge current testing options include: 10 cycles at 25ºC, or 10-cycles at -55ºC and +85ºC. Both standard and low ESR options are available. All lots of this series are conditioned with MIL-PRF-55365 Group A testing. T494 Series — Low ESR, Industrial Grade The T494 is a low ESR series that is available in all the same case sizes and CV ratings as the popular T491 series. The T494 offers low ESR performance with the economy of an industrial grade device. This series is targeted for output filtering and other applications that may benefit from improved efficiency due to low ESR. T495 Series — Low ESR, Surge Robust The low ESR, surge robust T495 series is an important member of KEMET’s tantalum chip family. Designed primarily for output filtering in switch-mode power supplies and DC-to-DC converters, the standard CV T495 values are also an excellent choice for batteryto-ground input filter applications. This series builds upon proven technology used for industrial grade tantalum chip capacitors to offer several important advantages: very low ESR, high ripple current capability, excellent capacitance stability, plus improved ability to withstand high inrush currents. These benefits are achieved through a combination of proprietary design, material, and process parameters, as well as high-stress, low impedance electrical conditioning performed prior to screening. Capacitance values range from 4.7µF to 1000µF, in voltage ratings from 2.5 to 50 volts. T496 Series — Fused KEMET also offers a “fail-safe” fused solid tantalum chip capacitor. The built-in fuse element provides excellent protection from damaging short circuit conditions in applications where high fault currents exist. Protection from costly circuit damage due to reversed installation is offered with this device. Package sizes include the EIA standard 3528-12, 6032-15, 7343-31, and 7343-43 case size. Capacitance values range from 0.15 µF to 470.0 µF, in voltage ratings from 4 to 50. Standard capacitance tolerances include ±20% and ±10%. Tape and reeling per EIA 481-1 is standard. 3 ©KEMET Electronics Corporation, P.O. Box 5928, Greenville, S.C. 29606, (864) 963-6300 TANTALUM CHIP CAPACITORS PRODUCT DESCRIPTION T498 SERIES - High Temperature (150° C) The T498 Series is a high temperature version of KEMET's solid tantalum chip family that offers optimal performance in applications with operating temperatures of up to 150° C. Advancements in materials and testing have allowed for the introduction of this series which delivers a reliability level of 0.5% per 1000 hours at rated voltage at rated temperature. This series is available in five standard EIA case sizes with RoHSCompliant/100% matte tin finish lead terminations as standard. Other termination options include 90Sn/10Pb finishes and gold for conductive adhesive attachment processes. Capacitance values range from .47µF to 220µF, in voltage ratings from 4 to 50 volts. T510 Series — High Capacitance – Low ESR The ultra-low ESR T510 Series is a breakthrough in solid tantalum capacitor technology. KEMET’s T510 Series offers low ESR in the popular EIA 7343-43 and 7360-38 case sizes. The ultra-low ESR and high ripple current capability make the T510 an ideal choice for SMPS filtering and power decoupling of today’s high speed microprocessors. KEMET has developed an innovative construction platform that incorporates multiple capacitor elements, in parallel, inside a single package. This unique assembly, combined with KEMET’s superior processing technology, provides the best combination of high CV, low ESR, and small size in a user friendly, molded, surface mount package. T520 SERIES — Conductive Polymer The Kemet Organic Capacitor (KO-CAP) is a Tantalum capacitor, with a Ta anode and Ta 2O 5 dielectric. However, a conductive, organic, polymer replaces the MnO2 as the cathode plate of the capacitor. This results in very low ESR and improved cap retention at high frequency. The KO-CAP also exhibits a benign failure mode, which eliminates the ignition failures that can occur in standard MnO2 Tantalum types. Note also that KO-CAPs may be operated at voltages up to 90% of rated voltage for part types with rated voltage ≤ 10 volts and up to 80% of rated voltage for part types > 10 volts with equivalent or better reliability than standard tantalums operated at 50% of rated voltage. The T520 series captures the best features of multilayer ceramic caps (low ESR and high frequency cap retention), aluminum electrolytics (benign failure mode), and proven solid tantalum technology (volumetric efficiency, surface mount capability, and no wearout mechanism). The KO-CAP can reduce component counts, eliminate through-hole assembly by replacing cumbersome leaded aluminum capacitors, and offer a more cost effective solution to high-cost high-cap ceramic capacitors. These benefits allow the designer to save both board space and money. See pages 42-52 for complete details. T525 SERIES — High Temperature Conductive Polymer The T525 Series is a version of KEMET’s Tantalum Polymer Capacitor rated up to 125ºC. This part type was introduced as Lead (Pb) Free and offers the same advantages as the T520 KO-CAP. This includes low ESR, high frequency capacitance retention and benign failure mode. T530 SERIES — Conductive Polymer High Capacitance — Ultra Low ESR KEMET is offering a multiple anode tantalum chip capacitor with a polymer material replacing the MnO2 offering non-ignition, self-healing, 125 C performance capability with higher conductivity material that lowers the ESR. Packaged as multiple anodes to reduce the depth that the signal must penetrate, this parallel arrangement reduces the ESR further still to achieve the highest capacitance and lowest ESR of any other type of SMT capacitor with typical ESR values as low as 5 milliohms. With the reduced ESR, the enhanced capacitance retention in higher frequencies results in the lowest total capacitance solution and provides for the most economical solution in high power applications. 4 ©KEMET Electronics Corporation, P.O. Box 5928, Greenville, S.C. 29606, (864) 963-6300 SOLID TANTALUM CHIP CAPACITORS TANTALUM MnO2 COMPONENT PERFORMANCE CHARACTERISTICS Introduction KEMET solid tantalum capacitors are identified by the initial “T,” followed by a unique “Series” number; for example, T491, T492, etc. Each Series denotes a general physical form and type of encapsulation, as well as limits on dimensions and certain electrical characteristics under standard conditions of 25°C, 50% relative humidity, and one atmosphere pressure. Specific requirements are set forth in the respective Product Series in this catalog. All series are 100% screened for leakage, capacitance, dissipation factor, and ESR. All Series are inspected to electrical limits using a minimum .1% AQL sampling plan, according to the Military Standard MIL-STD-105, even after 100% testing. This sampling plan, to the best of KEMET Electronics’ knowledge, meets or exceeds the generally accepted industry standard for similar products. KEMET capacitors may also be supplied, with prior agreement, to meet specifications with requirements differing from those of KEMET catalogs. of equilibrium with the environment, is approximately -5% to +12% over the range from 25% to 95% RH, referred to the standard 50% RH. The amount of change is dependent upon size (capacitance and voltage rating, ie: CV product); small sizes might change no more than ±5%. Equilibrium at such extremes is seldom attained by plastic-cased capacitors, and the change in capacitance is consequently less. The rate of response to humidity changes increases with increasing temperature. Dissipation factor and ESR also increase with increasing RH. DC leakage current may rise upon exposure to a combination of high temperature and high humidity, but is normally restored by voltage conditioning under standard conditions. The increase will be greater than that experienced under temperature influence alone because of conduction through absorbed water. Tantalum chips may be affected by absorption of water on external insulating surfaces.The water film may also attract a layer of dust from the air, increasing the effect. The most sensitive parameter is leakage current. 4. Capacitance • 0.1 µF to 1000 µF Refer to part number tables for available capacitance ratings and tolerances by series. Capacitance is measured at 120 Hz, up to 1.0 volt rms maximum and up to 2.5 volts DC maximum, at +25°C.DC bias causes only a small reduction in capacitance, up to about 2% when full rated voltage is applied. DC bias is not commonly used at room temperature, but is more commonly used at elevated temperatures. Capacitance decreases with increasing frequency. Solid Tantalum Surface Mount ELECTRICAL 1. General Application Class Solid tantalum capacitors are usually applied in circuits where the AC component is small compared to the DC component. Typical uses known to KEMET Electronics include blocking, by-passing, decoupling, and filtering. They are also used in timing circuits. General purpose devices are recommended to have an external series resistance of 0.1Ω/volt to reduce the failure due to surge current. Newer devices designed for power applications (T495, T5XX), are built to eliminate this series resistance requirement. Because tantalum capacitors can experience scintillation (self-healing) in their life, the circuit impedence should not exceed 100KΩ or this will circumvent the scintillation and degrade leakage. 2. Operating Temperature Range • –55 °C to +125 °C Voltage derating is specified in Section 5. Performance characteristics over this temperature range are presented within the following sections. 3. Non-Operating Temperature Range • –55 °C to +125 °C Tantalum capacitors do not lose capacitance from the “de-forming” effect as do liquid-electrolytic capacitors. Storage at high temperature may cause a small, temporary increase in leakage current (measured under standard conditions), but the original value is usually restored within a few minutes after application of rated voltage. Tantalum chips are not hermetically sealed, therefore they do exhibit reversible changes in parameters with respect to relative humidity (RH). Capacitance increases with increasing humidity. The limiting change, reached upon establishment FIGURE 1 Typical Effect of Frequency upon Capacitance Capacitance increases with increasing temperature.

The surge voltage is applied for 1000 cycles of 30 seconds at voltage through a 33 ohm series resistor and 30 seconds off voltage with the capacitor discharged through a 33 ohm resistor. Upon completing the test, the capacitors are allowed to stabilize at room temperature. Capacitance, DCL and DF are then tested: a. Capacitance — within ± 5% of initial value b. DC Leakage — within initial limit c. Dissipation Factor — within initial limit d. ESR — within initial limit 7.

Working DC Voltage (WVDC) • 3 to 50 volts Refer to part number tables for available voltage ratings by series. These voltages are the maximum recommended peak DC operating voltages from –55°C to +85°C for continuous duty. These voltages are derated linearly above +85°C to 2/3 rated voltage for operation at +125°C (See Figure 3). For added reliability it is recommended to operate at a 50% derating of the working voltage for tantalum capacitors with MnO2 as a cathode. See page 39 for working DC Voltage of high temperature T498 product. 100% Percent Change in Working DC Voltage 80% 60% 40% 20% Solid tantalum capacitors are polarized devices and may be permanently damaged or destroyed if connected with the wrong polarity. The positive terminal is identified on the capacitor body by a stripe and a beveled edge. A small degree of transient reverse voltage is permissible for short periods per Table 3. The capacitors should not be operated continuously in reverse mode, even within these limits. 8. DC Leakage Current (DCL) Refer to part number tables for maximum leakage current limits. DC leakage current is the current that, after a oneto five-minute charging period, flows through a capacitor when voltage is applied. Leakage is measured at +25°C with full rated DC voltage applied to the capacitor through a 1000 ohm resistor in series with the capacitor. DC leakage current increases with increasing temperature.

It is the ratio of the equivalent series resistance (ESR) to the capacitive reactance, (XC) and is usually expressed as a percentage. It is directly proportional to both capacitance and frequency. Dissipation factor loses its importance at higher frequencies, (above about 1 kHz), where impedance (Z) and equivalent series resistance (ESR) are the normal parameters of concern. DF = R = 2 fCR DF = Dissipation Factor XC R = Equivalent Series Resistance (Ohms) X C = Capacitive Reactance (Ohms) f = Frequency (Hertz) C = Series Capacitance (Farads) DF is also referred to as tan or “loss tangent.” The “Quality Factor,” “Q,” is the reciprocal of DF. DF decreases with temperature above +25°C and may also increase at lower temperatures. Unfortunately, one general limit for DF cannot be specified for all capacitance/voltage combinations, nor can response to temperature be simply stated. DC bias is not commonly used at room temperature, but is more commonly used at elevated temperatures. 10. Equivalent Series Resistance (ESR) and Impedance (Z) Equivalent Series Resistance (ESR) is the preferred high-frequency statement of the resistance unavoidably appearing in these capacitors. ESR is not a pure resistance, and it decreases with increasing frequency. Total impedance of the capacitor is the vector sum of capacitive reactance (XC) and ESR, below resonance; above resonance total impedance is the vector sum of inductive reactance (XL) and ESR. 7 0.01 0.001 0 10 20 30 40 50 60 70 80 90 100 110 Percentage of Rated Voltage FIGURE 5 Typical Effect of Applied Voltage on DC Leakage Current. 9. Dissipation Factor (DF) Refer to part number tables for maximum DF limits. Dissipation factor is measured at 120 Hz, up to 1.0 volt rms maximum, and up to 2.0 volts DC maximum at +25°C. The application of DC bias causes a small reduction in DF, about 0.2% when full rated voltage is applied. DF increases with increasing frequency. ©KEMET Electronics Corporation, P.O.

ESR — Represents the actual ohmic series resistance in series with the capacitance. Lead wires and capacitor electrodes are contributing sources. RL — Capacitor Leakage Resistance. Typically it can reach 50,000 megohms in a tantalum capacitor. It can exceed 1012 ohms in monolithic ceramics and in film capacitors. Rd — The dielectric loss contributed by dielectric absorption and molecular polarization. It becomes very significant in high frequency measurements and applications. Its value varies with frequency. Cd — The inherent dielectric absorption of the solid tantalum capacitor which typically equates to 1-2% of the applied voltage. As frequency increases, XC continues to decrease according to its equation above. There is unavoidable inductance as well as resistance in all capacitors, and at some point in frequency, the reactance ceases to be capacitive and becomes inductive. This frequency is called the self-resonant point. In solid tantalum capacitors, the resonance is damped by the ESR, and a smooth, rather than abrupt, transition from capacitive to inductive reactance follows. Typical ESR/Z frequency response curves are shown in Figures 9a and 9b. These curves are for selected ratings and represent typical T491 Series performance. Maximum limits for 100 kHz ESR are listed in the part number tables for each series. Note that the T494 Series offers low ESR and the T495 Series is specially designed for very low ESR performance. Refer to page 31 for more information. See also KEMET’s T510 Series low ESR ratings on page 40.

AC Operation Permissible AC ripple voltage and current are related to equivalent series resistance (ESR) and power dissipation capability. Permissible AC ripple voltage which may be applied is limited by three criteria: a. The positive peak AC voltage plus the DC bias voltage, if any, must not exceed the DC voltage rating of the capacitor. b. The negative peak AC voltage, in combination with the bias voltage, if any, must not exceed the permissible reverse voltage ratings presented in Table 3. c. The power dissipated in the ESR of the capacitor must not exceed the appropriate value specified in Table 5. Actual power dissipated may be calculated from the following: P =l R Substituting I = E , P = E2R Z Z2 where: I = rms ripple current (amperes) E = rms ripple voltage (volts) P = power (watts) Z = impedance at specified frequency (ohms) R = equivalent series resistance at specified frequency (ohms) Using P max from Table 5, maximum allowable rms ripple current or voltage may be determined as follows: P max/ P max/ I (max) = R E (max) = Z R These values should be derated at elevated temperatures as follows: Temperature Derating Factor 85 C .9 125 C .4 2 FIGURE 9b ESR & Impedance (z) vs Frequency ESR and Z are also affected by temperature. At 100 kHz, ESR decreases with increasing temperature. The amount of change is influenced by the size of the capacitor and is generally more pronounced on smaller ratings. 10 Multiplier of 100KHz ESR 1 0.1 -50 -25 0 25 50 75 100 125 Temperature - Degrees Centigrade FIGURE 10 Typical Effect of Temperature on 100 kHz ESR 11. AC Power Dissipation Power dissipation is a function of capacitor size and materials. Maximum power ratings have been established for all case sizes to prevent overheating. In actual use, the capacitor’s ability to dissipate the heat generated at any given power level may be affected by a variety of circuit factors. These include board density, pad size, heat sinks and air circulation.

Long Term Stability Within the general class of electrolytic capacitors, solid tantalum capacitors offer unusual stability of the three important parameters: capacitance, dissipation factor and leakage current. These solidstate devices are not subject to the effects of electrolysis, deforming or drying-out associated with liquid-electrolyte capacitors. When stabilized for measurement at standard conditions, capacitance will typically change less than ±3% during a 10,000 hour life test +85°C. 10 The same comparative change has been observed in shelf tests at +25°C extending for 50,000 hours. (Some of this change may stem from instrument or fixture error.) Dissipation factor exhibits no typical trend. Data from 10,000 hour life test at +85°C show that initial limits (at standard conditions) are not exceeded at the conclusion of these tests. Leakage current is more variable than capacitance or DF; in fact, leakage current typically exhibits a logarithmic dependence in several respects. Military Specifications permit leakage current (measured at standard conditions) to rise by a factor of four over 10,000 hour life tests. Typical behavior shows a lower rate of change, which may be negative or positive. Initial leakage currents are frequently so low (less than 0.1 nanoampere in the smallest CV capacitors) that changes of several orders of magnitude have no discernable effect on the usual circuit designs. 18. Failure Mode Capacitor failure may be induced by exceeding 50% of rated voltage of the capacitor with forward DC voltage, reverse DC voltage, power dissipation, or temperature. As with any practical device, these capacitors also possess an inherent, although low, failure rate when operated at less than 50% of the rated voltage of the capacitor. The dominant failure mode is by short-circuit. Minor parametric drifts are of no consequence in circuits suitable for solid tantalum capacitors. Catastrophic failure occurs as an avalanche in DC leakage current over a short (millisecond) time span. The failed capacitor, while called “short-circuited”, may exhibit a DC resistance of 10 to 104 ohm. If a failed capacitor is in an unprotected lowimpedance circuit, continued flow of current through the capacitor may obviously produce severe overheating. The over-heated capacitor may damage the circuit board or nearby components. Protection against such occurrence is obtained by current-limiting devices or fuses provided by the circuit design. KEMET’s T496 series offers a built-in fuse to convert the normal short circuit failure mode to an open circuit. Fortunately, the inherent failure rate of KEMET solid tantalum capacitors is low, and this failure rate may be further improved by circuit design. Statistical failure rates are provided for military capacitors. Relating circuit conditions to failure rate is aided by the guides in the section following. ©KEMET Electronics Corporation, P.O.

The structure of the AO-CAP uses aluminum as the anode material, aluminum oxide as the dielectric, and a conductive organic polymer for its counter-electrode material. The A700 series is 100% screened for all electrical parameters: Capacitance @ 120Hz, Dissipation Factor (DF) @ 120 Hz, ESR @ 100 kHz, and DC Leakage. The AO-CAP offers many advantages including extremely low ESR, high capacitance retention at high operating frequencies, no dry-out related failure mechanism and no voltage de-rating up to125°C. 4. Voltage Ratings • 2 - 10 VDC Rated Voltage This is the maximum peak DC operating voltage from -55°C to +125°C for continuous duty. Surge Voltage Ratings Surge voltage capability is demonstrated by application of 1000 cycles of the relevant voltage at 25°C, 85°C, or 125 °C. The parts are charged through a 33 ohm resistor for 30 seconds and then discharged through a 33 ohm resistor for 30 seconds for each cycle.

Reverse Voltage Rating & Polarity Aluminum polymer capacitors are polar devices and may be permanently damaged or destroyed if connected in the wrong polarity. The positive terminal is identified by a laser-marked stripe. These capacitors will withstand a certain degree of transient voltage reversal for short periods as shown in the following table. Please note that these parts may not be operated continuously in reverse, even within these limits. Table 2 Temperature 25°C 55°C 85°C 125°C Permissible Transient Reverse Voltage 60% of Rated Voltage 50% of Rated Voltage 40% of Rated Voltage 30% of Rated Voltage ELECTRICAL 1. Operating Temperature Range • -55°C to +125°C No derating with temperature is required. 2. Non-Operating Temperature Range • -55°C to 125°C 3. Capacitance and Tolerance • 22µF to 470µF • ±20% Tolerance Capacitance is measured at 120 Hz, up to 1.0 volt rms maximum and up to 2.5V DC maximum. DC bias causes only a small reduction in capacitance, up to about 2% when full rated voltage is applied. DC bias is not commonly used for room temperature measurements but is more commonly used when measuring at temperature extremes. Capacitance does decrease with increasing frequency, but not nearly as much or as quickly as standard tantalums. Figure 1 compares the frequency induced cap roll-off between the AO-CAP and traditional MnO2 types. Capacitance also increases with increasing temperature. See Section 12 for temperature coefficients. 6. DC Leakage Current Because of the high conductivity of the polymer, the AO-CAP family has higher leakage currents than traditional MnO2 type Tantalum caps. The DC Leakage limits at 25°C are calculated as 0.06 x C x V, (where C is cap in µF and V is rated voltage in Volts) for part types with rated voltage ≤ 4V, and equals 0.04 x C x V, for voltages > 4V. Limits for all part numbers are listed in the ratings tables. Figure 1. 58 ©KEMET Electronics Corporation, P.O. Box 5928, Greenville, S.C. 29606, (864) 963-6300 Aluminum Organic Capacitors ALUMINUM ORGANIC CAPACITORS Performance Characteristics DC Leakage Current is the current that flows through the capacitor dielectric after a five minute charging period at rated voltage. Leakage is measured at 25°C with full rated voltage applied to the capacitor through a 1000 ohm resistor in series with the capacitor. DC Leakage Current does increase with temperature. The limits for 85°C @ Rated Voltage and 125°C are both 2 times the 25°C limit. 7. Dissipation Factor (DF) Refer to part number tables for maximum DF limits. Dissipation factor is measured at 120 Hz, up to 1.0 volt rms maximum. Dissipation factor is the ratio of the equivalent series resistance (ESR) to the capacitive reactance, (Xc) and is usually expressed as a percentage. It is directly proportional to both capacitance and frequency. Dissipation factor loses its importance at higher frequencies, (above about 1 kHz), where impedance (Z) and equivalent series resistance (ESR) are the normal parameters of concern. R DF = X = 2πfCR c Where: DF = Dissipation Factor R = Equivalent Series Resistance (Ohms) Xc = Capacitive Reactance(Ohms) f = Frequency (Hertz) C = Capacitance (Farads) DF is also referred to as tan δ or "loss tangent." The "Quality Factor," "Q", is the reciprocal of DF. 8. Equivalent Series Resistance (ESR) and Impedance (Z) The Equivalent Series Resistance (ESR) of the AOCAP is much lower than standard Tantalum caps because the polymer cathode has much higher conductivity. ESR is not a pure resistance, and it decreases with increasing frequency. Total impedance of the capacitor is the vector sum of capacitive reactance (Xc) and ESR below reso nance; above resonance total impedance is the vector sum of inductive reactance (XL) and ESR. ESR Xc = 1 2πfC (Ohms) θ δ Where: f = frequency (Hertz) C = capacitance (Farad) Xc Figure 2a Total Impedance of the Capacitor Below Resonance XL = 2πfL (Ohms) Z XL δ θ ESR Figure 2b Total Impedance of the Capacitor Above Resonance To understand the many elements of a capacitor, see Figure 3. C ESL ESR RL Cd Rd Figure 3 The Real Capacitor A capacitor has a complex impedance consisting of many series and parallel elements, each adding to the complexity of the measurement system. ESL - Represents inductance. In most instances it is significant at the basic measurement frequencies of 120 and 1000 Hz. ESR - Represents the ohmic resistance in series with the capacitance. Lead attachment and capacitor electrodes are contributing sources. ©KEMET Electronics Corporation, P.O. Box 5928, Greenville, S.C. 29606, (864) 963-6300 59 Aluminum Organic Capacitors Where: f = frequency (Hertz) L = inductance (Henries) ALUMINUM ORGANIC CAPACITORS Performance Characteristics RL - Capacitor Leakage Resistance. Typically it can be 35 K to 2.5 MOhms depending on voltage capacitance. It can exceed 1012 ohms in monolithic ceramics and in film capacitors. Rd - The dielectric loss contributed by dielectric absorption and molecular polarization. It becomes very significant in high frequency measurements and applications. Its value varies with frequency. Cd - The inherent dielectric absorption of the solid aluminum capacitor. As frequency increases, Xc continues to decrease according to its equation. There is unavoidable inductance as well as resistance in all capacitors, and at some point in frequency, the reactance ceases to be capacitive and becomes inductive. This frequency is call the self-resonant point. Figure 4 compares the frequency response of an AO-CAP to a Tantalum chip. Maximum limits for 100 kHz ESR are listed in the part number tables for each series. 10. Ripple Current/Voltage Permissible AC ripple voltage and current are related to equivalent series resistance (ESR) and power dissipation capability. Permissible ripple current which may be applied is limited by two criteria: a. The resulting voltage across the capacitor with the summation of DC bias and peak voltage of the AC portion must not exceed the rated voltage of the capacitor. b. The negative peak AC voltage, in combination with bias voltage, if any, must not exceed the permissible reverse voltage ratings presented in Section 5. Actual power dissipated may be calculated from the following: P = I 2R Substituting I = E ; P = E2R Z Z2 Using P max from Table 3, maximum allowable rms ripple current or voltage may be determined as follows: Figure 4. 9. AC Power Dissipation Power dissipation is a function of capacitor size and materials. Maximum power ratings have been established for all case sizes to prevent overheating. In actual use, the capacitor's ability to dissipate the heat generated at any given power level may be affected by a variety of circuit factors. These include board density, pad size, heat sinks and air circulation. Power capability is determined based on a 20°C temperature rise. A higher temperature rise and therefore higher power capability is allowable as long as the ambient temperature plus temperature rise due to ripple current does not exceed the rated temperature of the part.

Temperature Stability Mounted capacitors withstand extreme temperature testing at a succession or continuous steps at +25°C, -55°C, +25°C, +85°C, +125°C, +25°C in that order.

Failure Mechanism and Reliability The normal failure mechanism is dielectric break down. Dielectric failure can result in high DC Leakage current and may proceed to the level of a short circuit. With sufficient time to charge, healing may occur by one of two potential mechanisms. The polymer adjacent to the dielectric fault site may overheat and vaporize, disconnecting the fault site from the circuit. The polymer may also oxidize into a more resistive material that caps the defect site in the dielectric and reduces the flow of current. Capacitor failure may be induced by exceeding the rated conditions of forward DC voltage, reverse DC voltage, surge current, power dissipation or temperature. Excessive environmental stress, such as prolonged or high temperature reflow processes may also trigger dielectric failure. 20.

Handling Automatic handling of encapsulated components is enhanced by the molded case which provides compatibility with all types of high speed pick and place equipment. Manual handling of these devices presents no unique problems. Care should be taken with your fingers, however, to avoid touching the soldercoated terminations as body oils, acids and salts will degrade the solderability of these terminations. Finger cots should be used whenever manually handling all solderable surfaces. 29. Termination Coating The standard finish coating is 100% Sn solder (Tin-solder coated) with nickel (Ni) underplating. 30. Recommended Mounting Pad Geometries Proper mounting pad geometries are essential for successful solder connections. These dimensions are highly process sensitive and should be designed to maximize the integrity of the solder joint, and to minimize component rework due to unacceptable solder joints. Figure 5 illustrates pad geometry. The table provides recommended pad dimensions for reflow soldering techniques. These dimensions are intended to be a starting point for circuit board designers, to be fine tuned, if necessary, based upon the peculiarities of the soldering process and/or circuit board design.

Soldering The A700 - AO-CAP family has been designed for reflow solder processes, or for wave soldering. The solder-coated terminations have excellent wetting characteristics for high integrity solder fillets. Preheating of these components is recommended to avoid extreme thermal stress. Figure 6 represents the recommended maximum solder temperature/ time combinations for these devices. Hand-soldering should be avoided. However, if necessary it should be performed with care due to the difficulty in process control. Care should be taken to avoid contact of the soldering iron to the molded case. The iron should be used to heat the solder pad, applying solder between the pad and the termination, until reflow occurs. The iron should be removed. "Wiping" the edges of a chip and heating the top surface is not recommended. 300 Temperature (°C) 34. Storage Environment AO capacitors are shipped in moisture barrier bags with a desiccant and mositure indicator card. This series is classified as MSL3 (Moisture Sensitivity Level 3). Upon opening the moisture barrier bag, parts should be mounted within 7 days to prevent mositure absorption and outgassing. If the 7 day window is exceeded, the parts can be dryed per the instructions on the bag (168 hours at 40 ± 5°C). AO capacitors should be stored in normal working environments. While the chips themselves are quite robust in other environments, solderability will be degraded by exposure to high temperatures, high humidity, corrosive atmospheres, and long term storage. In addition, packaging materials will be degraded by high temperature (reels may soften or warp, and tape peel force may increase). KEMET recommends that maximum storage temperature not exceed 40 degrees C, and the maximum storage humidity not to exceed 60% relative humidity. In addition, temperature fluctuations should be minimized to avoid condensation on the parts, and atmospheres should be free of chlorine and sulfur bearing compounds. For optimized solderability, chip stock should be used promptly, preferably within 1.5 years of receipt. Sn-Pb Profile Sn-Pb 5 Sec.

Washing Standard washing techniques and solvents are compatible with all KEMET surface mount aluminum capacitors. Solvents such as Freon TMC and TMS, Trichlorethane, methylene chloride, prelate, and isopropyl alcohol are not harmful to these components. Please note that we are not endorsing the use of banned or restricted solvents. We are simply stating that they would not be harmful to the components. If ultrasonic agitation is utilized in the cleaning process, care should be taken to minimize energy levels and exposure times to avoid damage to the terminations. KEMET AO-CAPS are also compatible with newer aqueous and semi-aqueous processes. 33. Encapsulations Under normal circumstances, potting or encapsulation of KEMET aluminum chips is not required.

The entire structure is then fired at high temperature to produce a monolithic block which provides high capacitance values in a small physical volume. After firing, conductive terminations are applied to opposite ends of the chip to make contact with the exposed electrodes. Standard end terminations use a nickel barrier layer and a tin overplate to provide excellent solderability for the customer. KEMET multilayer ceramic chip capacitors are produced in plants designed specifically for chip capacitor manufacture. The process features a high degree of mechanization as well as precise controls over raw materials and process conditions. Manufacturing is supplemented by extensive Technology, Engineering and Quality Assurance programs. KEMET ceramic chip capacitors are offered in the five most popular temperature characteristics. These are designated by the Electronics Industies Association (EIA) as the ultra-stable C0G (also known as NP0, military version BP), the stable X7R (military BX or BR), the stable X5R, and the general purpose Z5U and Y5V. A wide range of sizes are available. KEMET multilayer ceramic chip capacitors are available in KEMET's tape and reel packaging, compatible with automatic placement equipment. Bulk cassette packaging is also available (0805,0603 and 0402 only) for those pick and place machines requiring its use.

ELECTRICAL CHARACTERISTICS 1. Working Voltage: Refers to the maximum continuous DC working voltage permissible across the entire operating temperature range. The reliability of multilayer ceramic capacitors is not extremely sensitive to voltage, and brief applications of voltage above rated will not result in immediate failure. However, reliability will be degraded by sustained exposure to voltages above rated. Temperature Characteristics: Within the EIA classifications, various temperature characteristics are identified by a three-symbol code; for example: C0G, X7R, X5R, Z5U and Y5V. For Class I temperature compensating dielectrics (includes C0G), the first symbol designates the significant figures of the temperature coefficient in PPM per degree Celsius, the second designates the multiplier to be applied, and the third designates the tolerance in PPM per degrees Celsius. EIA temperature characteristic codes for Class I dielectrics are shown in Table 1. Capacitance Tolerance: See tables on pages 73-76. Capacitance: Within specified tolerance when measured per Table 3. The standard unit of capacitance is the farad. For practical capacitors, capacitance is usually expressed in microfarads (10 -6 farad), nanofarads (10 -9 farad), or picofarads (10 -12 farad). Standard measurement conditions are listed in Table 3 Specified Electrical Limits. Like all other practical capacitors, multilayer ceramic capacitors also have resistance and inductance. A simplified schematic for the single frequency equivalent circuit is shown in Figure 1. At high frequency more complex models apply see KEMET SPICE models at www.kemet.com for details. 2. ©KEMET Electronics Corporation, P.O.

Impedance: Since the parallel resistance (IR) is normally very high, the total impedance of the capacitor can be approximated by: Figure 3 ESL ESR C C = Capacitance ESL = Equivalent Series Inductance ESR = Equivalent Series Resistance IR = Insulation Resistance 2 2 Z= ESR + (X - X ) LC Where : Z = Total Impedance 5. Dissipation Factor: Measured under same conditions as capacitance. (See Table 3) Dissipation factor (DF) is a measure of the losses in a capacitor under AC application. It is the ratio of the equivalent series resistance to the capacitive reactance, and is usually expressed in percent. It is normally measured simultaneously with capacitance, and under the same conditions. The vector diagram below illustrates the relationship between DF, ESR and impedance. The reciprocal of the dissipation factor is called the “Q” or quality factor. For convenience, the “Q” factor is often used for very low values of dissipation factor especially when measured at high frequencies. DF is sometimes called the “loss tangent” or “tangent ”, as shown in Figure 2. ESR = Equivalent Series Resistance X = Capacitive Reactance = 1/(2 πfC) C X = Inductive Reactance = (2 πf) (ESL) L The variation of a capacitor's impedance with frequency determines its effectiveness in many applications. At high frequency more detailed models apply see KEMET SPICE models for such instances. 7. Figure 2 ESR DF(%) = ESR x 100 Xc X c O δ Ζ 1 Xc = 2 π fC Insulation Resistance: Measured after 2 minutes electrification at 25°C and rated voltage: Limits per Table 3. Insulation Resistance is the measure of a capacitor to resist the flow of DC leakage current. It is sometimes referred to as “leakage resistance”. Insulation resistance (IR) is the DC resistance measured across the terminals of a capacitor, represented by the parallel resistance (IR) shown in Figure 1. For a given dielectric type, electrode area increases with capacitance, resulting in a decrease in the insulation resistance. Consequently, insulation resistance limits are usually specified as the “RC” (IR x C) product, in terms of ohmfarads or megohm-micro-farads. The insulation resistance for a specific capacitance value is determined by dividing this product by the capacitance. However, as the nominal capacitance values become small, the insulation resistance calculated from the RC product reaches values which are impractical. Consequently, IR specifications usually include both a minimum RC product and a maximum limit based on the IR calculated Table 3 – Specified Electrical Limits Parameter Capacitance & Dissipation Factor: Measured at following conditions: C0G – 1kHz and 1 vrms if capacitance >1000 pF 1MHz and 1 vrms if capacitance ≤1000 pF X7R/X5R/Y5V – 1kHz and 1 vrms* if capacitance ≤ 10 µF X7R/X5R/Y5V – 120Hz and 0.5 vrms if capacitance > 10 µF Z5U – 1kHz and 0.5 vrms C0G Temperature Characteristics Z5U X7R/X5R Y5V DF Limits: **X5R
