CAPACITOR ELECTRICAL PERFORMANCE CHARACTERISTICS
ITEM PERFORMANCE CHARACTERISTICS
Category temperature range -55 °C to +85 °C (to +125 °C with voltage derating)
Capacitance tolerance ± 20 %, ± 10 %. Tested via bridge method, at +25 °C, 120 Hz
Dissipation factor Limit per Standard Ratings table. Tested via bridge method, at 25 °C, 120 Hz
ESR Limit per Standard Ratings table. Tested via bridge method, at 25 °C, 100 kHz
Leakage current After application of rated voltage applied to capacitors for 5 min using a steady source of power with
1 kΩ resistor in series with the capacitor under test, leakage current at 25 °C is not more than 0.01 CV or
0.5 μA, whichever is greater. Note that the leakage current varies with temperature and applied voltage.
See graph below for the appropriate adjustment factor.
Capacitance change by
temperature
+20 % max. (at +125 °C)
+10 % max. (at +85 °C)
-10 % max. (at -55 °C)
Reverse voltage Capacitors are capable of withstanding peak voltages in the reverse direction equal to:
10 % of the DC rating at +25 °C
5 % of the DC rating at +85 °C
Vishay does not recommend intentional or repetitive application of reverse voltage
Ripple current For maximum ripple current values (at 25 °C) refer to relevant datasheet. If capacitors are to be used at
temperatures above +25 °C, the permissible RMS ripple current (or voltage) shall be calculated using the
derating factors:
1.0 at +25 °C; 0.9 at +85 °C; 0.4 at +125 °C
