Ripple current

The following values are approximate only, to give an

indication of the effects of frequency and

temperature on ripple current. More accurate data

can be obtained by referring to the Application Notes

available from BHC Aerovox.

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 multipliers should be

applied to the 100Hz ripple current.
