Time to do some capacitor replacments and have a question about ripple current..
The way I understand it generally higher ripple current capacity is better as caps will last longer..
But on digikey ripple current has 2 measurments..
Low frequency @120hz
High frequency @ 100khz
I am assuming these different specs would be for different use cases like basic power delivery vs power smoothing? Is that correct?
I am switching to polymer caps so esr is low.
Should I be focusing more on the 100khz ripple rating?
