Are there no other situations where ripple current matters? Perhaps
unusual
power HF systems?
** The " ripple current" rating matters whenever ANY capacitor is passing
significant amounts of current - such that its ESR causes it to self heat.
Cap makers do not publish ripple current figures for all types, but usually
do publish ESR values and curves from which the amount of self heating can
be calculated - at least approximately.
Ignore this at your peril - eg:
The common X cap for mains suppression is well designed for its job, with
250 volts AC at 50 or 60Hz - but what say if you apply that same voltage
at 10kHz ??
Answer - it smokes and explodes.
