The effective ESR of the capacitors follows the parallel resistor rule. For example, if one capacitor''s ESR is 1 Ohm, putting ten in parallel makes the effective ESR of the capacitor bank ten times smaller. This is especially helpful if you expect a high ripple current on the capacitors. Cost saving. Let''s say you need a large amount of ...

New Energy Sources WhatsAppA decoupling capacitor''s job is to supress high-frequency noise in power supply signals. They take tiny voltage ripples, which could otherwise be harmful to delicate ICs, out of the voltage supply. In a way, decoupling capacitors act as a very small, local power supply for ICs (almost like an uninterruptible power supply is to computers). If ...
