Notes

• All information presented in this document reflects typical performance characteristics

Note

• For temperatures above +85 °C the same voltage derating ratio is recommended, but with respect to category voltage.

Up to +85 °C: category voltage = rated voltage

At +125 °C: category voltage = 2/3 of rated voltage

At 150 °C / 175 °C: category voltage = 1/2 of rated voltage

ELECTRICAL PERFORMANCE CHARACTERISTICS

PERFORMANCE CHARACTERISTICS

Category temperature range

-55 °C to +85 °C

Capacitance tolerance

± 20 %, ± 10 %, tested via bridge method, at 25 °C, 120 Hz

Dissipation factor

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

ESR

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 min 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 0.01 CV or 0.5 μA,

whichever is greater. Note that the leakage current varies with temperature and applied voltage. See graph

“Typical Leakage Current Temperature Factor” for the appropriate adjustment factor.

Capacitance change by

temperature

+30 % max. (at +175 °C)

+20 % max. (at +125 °C and +150 °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

1 % of the DC rating at +125 °C

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

0.3 at +150 °C

0.2 at +175 °C
