PERFORMANCE CHARACTERISTICS

Operating temperature range

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

Capacitor tolerance

± 20 %, ± 10 % at 120 Hz, at +25 °C

Capacitor change by temperature

Limit per Standard Ratings table

ESR

Limit per Standard Ratings table, at +25 °C, 120 Hz

Impedance

Limit per Standard Ratings table, at -55 °C, 120 Hz

DCL (leakage current)

Limit per Standard Ratings table

AC ripple current

Limit per Standard Ratings table, at +85 °C and 40 kHz

Reverse voltage

There shall be no continuous reverse voltage. Transient reverse voltage surges are acceptable under

the following conditions:

a) The peak reverse voltage is equal to or less than 1.5 V and the product of the peak current times

the duration of the reverse transient is 0.05 As or less

b) The repetition rate of the reverse voltage surges is less than 10 Hz

Surge voltage

Surge voltage shall be in accordance with MIL-PRF-39006 and Table I of DLA 10004.

The DC rated surge voltage is the maximum voltage to which the capacitors can be subjected under

any conditions including transients and peak ripple at the highest line voltage.

The DC surge voltage is 115 % of rated DC voltage.
