Abstract
A method of manufacturing an aluminum electrolytic capacitor includes impregnating an aluminum electrolytic capacitor with a first electrolyte to form a first impregnated capacitor, aging the first impregnated capacitor using a first aging process to form a first aged capacitor, impregnating the first aged capacitor with a second electrolyte to form a second impregnated capacitor, the second electrolyte being different from the first electrolyte, aging the second impregnated capacitor using a final aging process to form a final aged capacitor, and impregnating the final aged capacitor with a third electrolyte.
