CAPACITORS PERFORMANCE CHARACTERISTICS

Notes

• At + 25 °C, the leakage current shall not exceed the value listed in the Standard Ratings table

• At + 85 °C, the leakage current shall not exceed 10 times the value listed in the Standard Ratings table

• At + 125 °C, the leakage current shall not exceed 12 times the value listed in the Standard Ratings table

PERFORMANCE CHARACTERISTICS

Category Temperature Range

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

Capacitance Tolerance

Dissipation Factor (at 120 Hz)

Limits per Standard Ratings table. Tested via bridge method, at 25 °C, 120 Hz.

ESR (100 kHz)

Limits 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 minutes using a steady source of power with

1 k

Ω resistor in series with the capacitor under test, leakage current at 25 °C is not more than described

in Standard Ratings Table. Note that the leakage current varies with temperature and applied voltage. See

graph below for the appropriate adjustment factor.

Reverse Voltage

Capacitors are capable of withstanding peak voltages in the reverse direction equal to: 10 % of the DC

rating at + 25 °C or 5 % of the DC rating at + 85 °C.

Vishay does not recommended 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
