CAPACITOR ELECTRICAL PERFORMANCE CHARACTERISTICS

ITEM

PERFORMANCE CHARACTERISTICS

Category temperature range

- 55 °C to + 85 °C (to + 125 °C with voltage derating)

Capacitance tolerance

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 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
