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

ELECTRICAL PERFORMANCE CHARACTERISTICS

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.

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

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

1.0 at + 25 °C

0.9 at + 85 °C

0.4 at + 125 °C
