ESR means Equivalant Series Resistance. It is the resistance of the electrolyte and increases the impedance of the capacitor - which is a bad thing.Originally posted by billcrup@Jan 26 2005, 03:01 AM
I am trying to understand why the output capacitor in a switching regulator must be low ESR, and how that varies from ESI. Can anyone help?
