In Europe (RoHS Directive) and in some other geographical areas like China, legislation has been put in place to prevent the use of some hazardous materials, such as lead (Pb), in electronic equipment. All products in this catalog are produced to help our customers’ obligations to guarantee their products and fulfill these legislative requirements. The only material of concern in our products has been lead (Pb), which has been removed from all designs to fulfill the requirement of containing less than 0.1% of lead in any homogeneous material. KEMET will closely follow any changes in legislation world wide and make any necessary changes in its products, whenever needed. Some customer segments such as medical, military and automotive electronics may still require the use of lead in electrode coatings. To clarify the situation and distinguish products from each other, a special symbol is used on the packaging labels for RoHS compatible capacitors. Due to customer requirements, there may appear additional markings such as lead free (LF) or lead-free wires (LFW) on the label.

No voltage applied Voltage Performance Capacitance Change Dissipation Factor Leakage Current The following specifications will be satisfied when the capacitor is restored to 20°C: Within ±20% of the initial value Does not exceed 200% of the specified value Does not exceed specified value Shelf Life The capacitance, ESR and impedance of a capacitor will not change significantly after extended storage periods, however, the leakage current will very slowly increase. KEMET's E aluminum electrolytic capacitors should not be stored in high temperatures or where there is a high level of humidity. The suitable storage condition for KEMET's E aluminum electrolytic capacitors is +5 to +35°C and less than 75% in relative humidity. KEMET's E aluminum electrolytic capacitors should not be stored in damp conditions such as water, saltwater spray or oil spray. KEMET's E aluminum electrolytic capacitors should not be stored in an environment full of hazardous gas (hydrogen sulphide, sulphurous acid gas, nitrous acid, chlorine gas, ammonium, etc.) KEMET's E aluminum electrolytic capacitors should not be stored under exposure to ozone, ultraviolet rays or radiation. If a capacitor has been stored for more than 18 months under these conditions and it shows increased leakage current, then a treatment by voltage application is recommended. Re-Age (Reforming) Procedure Apply the rated voltage to the capacitor at room temperature for a period of one hour, or until the leakage current has fallen to a steady value below the specified limit. During re-aging a maximum charging current of twice the specified leakage current or 5 mA, whichever is greater, is suggested. © KEMET Electronics Corporation • KEMET Tower • One East Broward Boulevard Fort Lauderdale, FL 33301 USA • 954-766-2800 • www.kemet.com A4001_EDK • 11/13/2020 4 Surface Mount Aluminum Electrolytic Capacitors – EDK, +85°C Table 1 – Ratings & Part Number Reference VDC VDC Surge Voltage Rated Capacitance 120 Hz 20°C (µF) Case Size D x L (mm) DF 120 Hz 20°C (tan δ %) RC 120 Hz 85°C (mA) LC 20°C 2 Minutes (µA) Part Number 4 4 4 4 4 4 6.3 6.3 6.3 6.3 6.3 6.3 6.3 6.3 6.3 6.3 6.3 6.3 6.3 6.3 6.3 6.3 6.3 6.3 10 10 10 10 10 10 10 10 10 10 16 16 16 16 16 16 16 16 16 16 16 16 16 16 16 16 16 16 5 5 5 5 5 5 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 13 13 13 13 13 13 13 13 13 13 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 33 47 100 220 330 470 22 33 33 47 47 100 100 150 220 220 220 330 330 470 680 1000 1000 1500 22 33 33 47 100 220 330 470 470 1000 4.7 10 22 22 22 33 33 47 47 100 100 220 220 330 330 470 470 680 4 x 5.4 4 x 5.4 5 x 5.4 6.3 x 5.4 6.3 x 5.4 6.3 x 7.7 4 x 5.4 5 x 5.4 4 x 5.4 4 x 5.4 5 x 5.4 5 x 5.4 6.3 x 5.4 6.3 x 5.4 8 x 6.2 6.3 x 5.4 6.3 x 7.7 8 x 6.2 6.3 x 7.7 8 x 10.2 10 x 10.2 8 x 10.2 10 x 10.2 10 x 10.2 4 x 5.4 4 x 5.4 5 x 5.4 5 x 5.4 6.3 x 5.4 6.3 x 7.7 8 x 10.2 8 x 10.2 10 x 10.2 10 x 10.2 4 x 5.4 4 x 5.4 5 x 5.4 4 x 5.4 5 x 5.4 5 x 5.4 6.3 x 5.4 5 x 5.4 6.3 x 5.4 6.3 x 5.4 6.3 x 7.7 6.3 x 7.7 8 x 10.2 8 x 10.2 10 x 10.2 8 x 10.2 10 x 10.2 10 x 10.2 35 35 35 35 35 35 26 26 26 26 26 26 26 26 35 35 35 35 35 35 35 35 35 35 30 30 20 30 26 26 26 26 26 26 16 16 16 26 16 26 16 16 16 20 20 20 20 20 20 20 20 20 26 34 61 82 80 200 20 22 22 36 46 47 71 71 250 74 235 300 280 380 458 500 700 750 28 29 43 43 70 250 330 390 400 580 20 28 39 28 39 45 66 45 70 70 85 162 280 320 380 350 420 430 3.0 3.0 4.0 8.8 13.2 18.8 3.0 3.0 3.0 3.0 3.0 6.3 6.3 9.5 13.9 13.9 13.9 20.8 20.8 29.6 42.8 63.0 63.0 94.5 3.0 3.3 3.3 4.7 10.0 22.0 33.0 47.0 47.0 100.0 3.0 3.0 3.5 3.5 3.5 5.3 5.3 7.5 7.5 16.0 16.0 35.2 35.2 52.8 52.8 75.2 75.2 108.8 EDK336M004(1)9BAA EDK476M004(1)9BAA EDK107M004(1)9DAA EDK227M004(1)9GAA EDK337M004(1)9GAA EDK477M004(1)9HAA EDK226M6R3(1)9BAA EDK336M6R3(1)9DAA EDK336M6R3(1)9BAA EDK476M6R3(1)9BAA EDK476M6R3(1)9DAA EDK107M6R3(1)9DAA EDK107M6R3(1)9GAA EDK157M6R3(1)9GAA EDK227M6R3(1)9LAA EDK227M6R3(1)9GAA EDK227M6R3(1)9HAA EDK337M6R3(1)9LAA EDK337M6R3(1)9HAA EDK477M6R3(1)9MAA EDK687M6R3(1)9PAA EDK108M6R3(1)9MAA EDK108M6R3(1)9PAA EDK158M6R3(1)9PAA EDK226M010(1)9BAA EDK336M010(1)9BAA EDK336M010(1)9DAA EDK476M010(1)9DAA EDK107M010(1)9GAA EDK227M010(1)9HAA EDK337M010(1)9MAA EDK477M010(1)9MAA EDK477M010(1)9PAA EDK108M010(1)9PAA EDK475M016(1)9BAA EDK106M016(1)9BAA EDK226M016(1)9DAA EDK226M016(1)9BAA EDK226M016(1)9DAA EDK336M016(1)9DAA EDK336M016(1)9GAA EDK476M016(1)9DAA EDK476M016(1)9GAA EDK107M016(1)9GAA EDK107M016(1)9HAA EDK227M016(1)9HAA EDK227M016(1)9MAA EDK337M016(1)9MAA EDK337M016(1)9PAA EDK477M016(1)9MAA EDK477M016(1)9PAA EDK687M016(1)9PAA VDC VDC Surge Rated Capacitance Case Size DF RC LC Part Number (1) Insert Electrical Parameters code.

The oxygen produced by electrolysis will regenerate the dielectric layer but, at the same time, the hydrogen released may cause the internal pressure of the capacitor to increase. The overpressure vent, or safety vent, ensures that the gas can escape when the pressure reaches a certain value. All mounting positions must allow the safety vent to work properly. Installing • As a general principle, lower-use temperatures result in a longer, useful life of the capacitor. For this reason, it should be ensured that electrolytic capacitors are placed away from heat-emitting components. Adequate space should be allowed between components for cooling air to circulate, particularly when high ripple current loads are applied. In any case, the maximum category temperature must not be exceeded. • Do not deform the case of the capacitors or use capacitors with a deformed case. • Verify that the connections of the capacitors are able to insert on the board without excessive mechanical force. • If the capacitors require mounting through additional means, the recommended mounting accessories shall be used. • Verify the correct polarization of the capacitor on the board. • Verify that the space around the pressure relief device is according to the following guideline: Case Diameter Space Around Safety Vent ≤ 16 mm > 2 mm > 16 to ≤ 40 mm > 3 mm > 40 mm > 5 mm It is recommended that capacitors always be mounted with the safety device uppermost or in the upper part of the capacitor. • If the capacitors are stored for a long time, the leakage current must be verifi ed. If the leakage current is superior to the value listed in this catalog, the capacitors must be reformed. In this case, they can be reformed by application of the rated voltage through a series resistor approximately 1 kΩ for capacitors with VR ≤ 160 V (5 W resistor) and 10 kΩ for the other rated voltages. • In the case of capacitors connected in a series, a suitable voltage sharing must be used. In the case of balancing resistors, the approximate resistance value can be calculated as: R = 60/C. KEMET recommends, nevertheless, to ensure that the voltage across each capacitor does not exceed its rated voltage. © KEMET Electronics Corporation • KEMET Tower • One East Broward Boulevard Fort Lauderdale, FL 33301 USA • 954-766-2800 • www.kemet.com A4001_EDK • 11/13/2020 8 Surface Mount Aluminum Electrolytic Capacitors – EDK, +85°C Application and Operation Guidelines Electrical Ratings: Capacitance (ESC) Simplified equivalent circuit diagram of an electrolytic capacitor The capacitive component of the equivalent series circuit, (equivalent series capacitance - ESC), is determined by applying an alternate voltage of ≤ 0.5 V at a frequency of 120 or 100 Hz and 20°C (IEC 384-1, 384-4). Temperature Dependence of the Capacitance Capacitance of an electrolytic capacitor depends upon temperature: with decreasing temperature the viscosity of the electrolyte increases, thereby reducing its conductivity. Capacitance will decrease if temperature decreases. Furthermore, temperature drifts cause armature dilatation and, therefore, capacitance changes (up to 20% depending on the series considered, from 0 to 80°C). This phenomenon is more evident for electrolytic capacitors than for other types. Frequency Dependence of the Capacitance Effective capacitance value is derived from the impedance curve, as long as impedance is still in the range where the capacitance component is dominant. C= 1 2π fZ C = capacitance (F) f = frequency (Hz) Z = impedance (Ω) Dissipation Factor tan δ (DF) Dissipation Factor tan δ is the ratio between the active and reactive power for a sinusoidal waveform voltage. It can be thought of as a measurement of the gap between an actual and ideal capacitor. reactive ideal δ actual active Tan δ is measured with the same set-up used for the series capacitance ESC. Tan δ = ω x ESC x ESR where: ESC = Equivalent series capacitance ESR = Equivalent series resistance © KEMET Electronics Corporation • KEMET Tower • One East Broward Boulevard Fort Lauderdale, FL 33301 USA • 954-766-2800 • www.kemet.com A4001_EDK • 11/13/2020 9 Surface Mount Aluminum Electrolytic Capacitors – EDK, +85°C Equivalent Series Inductance (ESL) Equivalent series inductance or self inductance results from the terminal confi guration and internal design of the capacitor. Capacitor Equivalent Internal Circuit Equivalent Series Capacitance (ESC) Equivalent Series Resistance (ESR) Equivalent Series Inductance (ESL) Co Re L Equivalent Series Resistance (ESR) Equivalent series resistance is the resistive component of the equivalent series circuit. ESR value depends on frequency and temperature, and is related to the tan δ by the following equation: Ce ESR = tan δ 2πf ESC ESR = Equivalent series resistance (Ω) tan δ = Dissipation factor ESC = Equivalent series capacitance (F) f = Frequency (Hz) Tolerance limits of the rated capacitance must be taken into account when calculating this value. Impedance (Z) Impedance of an electrolytic capacitor results from a circuit formed by the following individual equivalent series components: Co Re L Ce Co = Aluminum oxide capacitance (surface and thickness of the dielectric.) Re = Resistance of electrolyte and paper mixture (other resistances not depending on the frequency are not considered: tabs, plates, etc.) Ce = Electrolyte soaked paper capacitance. L = Inductive reactance of the capacitor winding and terminals. Impedance of an electrolytic capacitor is not a constant quantity that retains its value under all conditions; it changes depending on frequency and temperature. Impedance as a function of frequency (sinusoidal waveform) for a certain temperature can be represented as follows: © KEMET Electronics Corporation • KEMET Tower • One East Broward Boulevard Fort Lauderdale, FL 33301 USA • 954-766-2800 • www.kemet.com A4001_EDK • 11/13/2020 10 Surface Mount Aluminum Electrolytic Capacitors – EDK, +85°C Impedance (Z) cont.

Impedance as a function of frequency (sinusoidal waveform) for different temperature values can be represented as follows (typical values): Z (ohm) 10 µF 1,000 100 -40°C 10 20°C 85°C 1 0.1 0.1 1 10 100 1,000 10,000 F (K H z) Re is the most temperature-dependent component of an electrolytic capacitor equivalent circuit. Electrolyte resistivity will decrease if temperature rises. In order to obtain a low impedance value throughout the temperature range, Re must be as little as possible. However, Re values that are too low indicate a very aggressive electrolyte, resulting in a shorter life of the electrolytic capacitor at high temperatures. A compromise must be reached. © KEMET Electronics Corporation • KEMET Tower • One East Broward Boulevard Fort Lauderdale, FL 33301 USA • 954-766-2800 • www.kemet.com A4001_EDK • 11/13/2020 11 Surface Mount Aluminum Electrolytic Capacitors – EDK, +85°C Leakage Current (LC) Due to the aluminum oxide layer that serves as a dielectric, a small current will continue to fl ow even after a DC voltage has been applied for long periods. This current is called leakage current. A high leakage current fl ows after applying voltage to the capacitor then decreases in a few minutes, for example, after prolonged storage without any applied voltage. In the course of continuous operation, the leakage current will decrease and reach an almost constant value. After a voltage-free storage the oxide layer may deteriorate, especially at a high temperature. Since there are no leakage currents to transport oxygen ions to the anode, the oxide layer is not regenerated. The result is that a higher than normal leakage current will fl ow when voltage is applied after prolonged storage. As the oxide layer is regenerated in use, the leakage current will gradually decrease to its normal level. The relationship between the leakage current and voltage applied at constant temperature can be shown schematically as follows: I VR VS VF V Where: VF = Forming voltage If this level is exceeded, a large quantity of heat and gas will be generated and the capacitor could be damaged. VR = Rated voltage This level represents the top of the linear part of the curve. VS = Surge voltage This lies between VR and VF. The capacitor can be subjected to VS for short periods only. Electrolytic capacitors are subjected to a reforming process before acceptance testing. The purpose of this preconditioning is to ensure that the same initial conditions are maintained when comparing different products. Ripple Current (RC) The maximum ripple current value depends on: • Ambient temperature • Surface area of the capacitor (heat dissipation area) tan δ or ESR • Frequency The capacitor’s life depends on the thermal stress. © KEMET Electronics Corporation • KEMET Tower • One East Broward Boulevard Fort Lauderdale, FL 33301 USA • 954-766-2800 • www.kemet.com A4001_EDK • 11/13/2020 12 Surface Mount Aluminum Electrolytic Capacitors – EDK, +85°C Frequency Dependence of the Ripple Current ESR and, thus, the tan δ depend on the frequency of the applied voltage. This indicates that the allowed ripple current is also a function of the frequency. Temperature Dependence of the Ripple Current The data sheet specifi es maximum ripple current at the upper category temperature for each capacitor.

Both the anode and cathode foils are then interleaved with absorbent paper and wound into a cylinder. During the winding process, aluminum tabs are attached to each foil to provide the electrical contact. The deck, complete with terminals, is attached to the tabs and then folded down to rest on top of the winding. The complete winding is impregnated with electrolyte before being housed in a suitable container, usually an aluminum can, and sealed. Throughout the process, all materials inside the housing must be maintained at the highest purity and be compatible with the electrolyte. Each capacitor is aged and tested before being sleeved and packed. The purpose of aging is to repair any damage in the oxide layer and thus reduce the leakage current to a very low level. Aging is normally carried out at the rated temperature of the capacitor and is accomplished by applying voltage to the device while carefully controlling the supply current. The process may take several hours to complete. Damage to the oxide layer can occur due to variety of reasons: • Slitting of the anode foil after forming • Attaching the tabs to the anode foil • Minor mechanical damage caused during winding A sample from each batch is taken by the quality department after completion of the production process. This sample size is controlled by the use of recognized sampling tables defi ned in BS 6001. The following tests are applied and may be varied at the request of the customer. In this case the batch, or special procedure, will determine the course of action.
