PERFORMANCE CHARACTERISTICS
Category temperature range - 55 °C to + 85 °C (to + 125 °C with voltage derating)
Capacitance tolerance
Dissipation factor
± 20 %, ± 10 % (at 120 Hz) 2 V_RMS (max.) at + 25 °C using a capacitance bridge
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 k 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
+ 12 % max. (at + 125 °C)
+ 10 % max. (at + 85 °C)
- 10 % max. (at - 55 °C)
For capacitance value > 300 μF
+ 20 % max. (at + 125 °C)
+ 15 % max. (at + 85 °C)
- 15 % 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
Temperature derating
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
Operating temperature
+ 85 °C
+ 125 °C
