Learn MoreThe requirement for "low-ESR" capacitors normally arises in output filters of switching power supplies, where the frequency is relatively high (kHz to MHz). It''s less important in mains filters (including the input filter of a SMPS) where a large capacity electrolytic tends to have a proportionally small ESR so that 100Hz or 120Hz ripple is not …
