FREQUENCY CORRECTION
Capacitors shall withstand the rated r.m.s. ripple
current as given in the tables at upper category
temperature in circulating air. For frequencies other
than those shown the following formula should be used:
Ripple current =
A = 100Hz ripple current
B = 10kHz ripple current
F = Required frequency (Hz)
TEMPERATURE CORRECTION
For ambient temperatures other than 85°C the
following multipliers should be applied to the 85°C
ripple current.
N.B. The sum of the d.c. and a.c. voltage components
should not exceed the d.c. voltage rating.
Life expectancy
At rated temperature with rated voltage and ripple
current applied.
