Limits to number of parallel smoothing capacitors in a power supply
Would there be any disadvantage (other than a high component count) to using seven 470 μF, 16 V electrolytic capacitors instead of one 3300 μF, 16 V capacitor to smooth power supply ripple?

For the capacitor specification "Ripple Current at Low Frequency" is a higher value better for a linear power supply?
I'm finding information that seems to be contradictory in various places, and I think people are talking about different ways of looking at the same spec.
The specification that Digikey uses to search/...

How do I caluclate which capacitor to use as a filter after the brdige rectifier using the 18Vpk A.C. 50 Hz as a source?
Like how would I go about on it? From calcualating the ripple voltage, to knowing which value of farads to use.

Ripple filter @ 2 amp without breaking the bank?
I'm trying to create a +160v and +/- 100v supply that with idle at 2A.
The problem I'm having is I can't find capacitors that can handle the ripple currents for the prefilter. I need to order like $...
