In Reply to: Replace large electrolytic capacitors with multiples smaller ones in parallel posted by jorisdallaire on October 31, 2023 at 11:13:55:
Large capacitors usually have a higher ripple current rating than small ones (both physical size and capacitance). Two 4,700µF caps will usually have a lower combined ripple current than a single 10,000µF cap, and will also show a lower ESR (equivalent series resistance). The combination will generally be cheaper as well - one of the very few instances where you really can get something for nothing. Using ten 1,000µF caps will generally give even better overall figures again, but the cost (in time and effort) of assembling them into a proper filter bank may not be felt worthwhile.
