CAP. CA55 SERIES CASE E APPLICATION NTOE Storage Condition 1) Environmental temperature：10°C～ +30°C 2) Relative humidity no more than 60% 3) Storing period: No more than one and half year since the date of stocking. Application Guide 1) Ripple Current and Voltage If the ripple current is applied to the capacitor, the Joule heat (power dissipated) will be generated in the capacitor, so it will affect the reliability of the capacitor. (1) Power Dissipated The actual power dissipated can be calculated using the following formula: P=I² × ESR………Formula 1 P: Power dissipated (W); I: Ripple current (A); ESR: Equivalent series resistance (Ω) Power Dissipation for Case E ( EIA Code 7343-43): 125mW Max. @+25°C (2) Ripple Current Using the maximum power dissipation 125mW Max., the ripple current can be calculated using the following formula: I= ×K×F…………Formula 2 K: Temperature derating factor......

CAP. CA55 SERIES CASE E (3) Ripple Voltage The ripple voltage applied to the capacitor is limited by three criteria. (a) The power dissipation in the ESR of capacitor must not exceed 125mW Max. @+25°C (b) The positive peak AC voltage plus the DC bias voltage must not exceed the DC voltage rating of the capacitor. (c) The negative peak AC voltage, in combination with the bias voltage, if any , must not exceed the permissible reverse voltage ratings presented . 2) Reverse Voltage Solid tantalum capacitors are polarized devices , and applied reverse voltage can not be allowed . If the reverse voltage is unavoidable, a small degree of transient reverse voltage is permissible for short periods as follow. 25°C……. 10% of Max. rated voltage or 1V whichever is smaller 85°C……. 5% of Max. rated voltage or 0.5V whichever is smaller 125°C……1% of Max. rated voltage or 0.1V whichever is smaller Even under these restrictions, capacitors can not be used continuously in reverse voltage mode. 3) Working Voltage (1) For general applications, using 50% of rated voltage of capacitors or less. (2) When used at the power circuit, low impedance circuit , coupling circuit or witching circuit which has leakage current problems, please design the circuit with voltage under 30% of the working voltage ( max 50%) to avoid the adverse effect of the surge current. (3) Derating voltage when temperature above 85°C. When the chip tantalum capacitor is used at 85℃ or more temperatures, the reduced voltage (UT) is calculated from the following expression, however, note that the ambient temperature is not more than 125℃. U T=V 0 (U R-U C)(T-85)/40 UR: Rated voltage (V); UC: Derating voltage at 125°C; T: Ambient temperature (°C ) 7 NextGen Components, Inc. sales@NextGenComponent.com www.NextGenComponent.com PART CODE: CA55E035K476TA SMD CONDUCTIVE POLYMER TANT. CAP. CA55 SERIES CASE E 4) Protective Resistance In a circuit(switching circuit, charge / discharge circuit, etc.) that has an instantaneous current, series resistance is at least 3Ω/V, this can improve the reliability of tantalum capacitors. If the capacitor is in a low impedance circuit, the voltage applied to the capacitor should be half or one third of the rated voltage. 5) Redundancy MnO2 tantalum capacitors will heat, and may cause fire and burn in the short circuit . This is determined by the situation, time and other factors. When the circuit is designed, it is possible to provide the best possible space to keep the tantalum capacitor reliability. 6) Test Condition Ambient Temperature 25°C; Relative Humidity 60 to 70%; Air Pressure 800 to 1060mbar. Test and experiment, in order to make the test results not problems, it is necessary to will test the product after fully discharge. This product is a polar components, testing or when using it is strictly prohibited to will is negative pick back, in order to avoid performance failure 7) Soldering The SMD tantalum capacitor can be used for reflow soldering, which is not suitable for wave soldering and manual welding. The reflow temperature are ≤250°C, ≤ 5 seconds. If you must use manual welding, should use the melted solder to contact lead, and the electric soldering iron power should be less than or equal to 25W, temperature should be less than 300℃, welding time should be less than 3 seconds, can not use electric iron contact the product lead directly, and in particular, can not contact the product ontology directly. Recommended profile conditions for convection and IR reflow reflect the profile conditions of the IPC/J-STD-020D standard for moisture sensitivity testing 8 NextGen Components, Inc. sales@NextGenComponent.com www.NextGenComponent.com PART CODE: CA55E035K476TA SMD CONDUCTIVE POLYMER TANT.
