Abstract:
1. A method for providing a filtered feedthrough, comprising the steps of: a) providing a feedthrough comprising: a conductive ferrule comprising an annular sidewall having a ferrule opening extending axially along the ferrule sidewall from a first end to a second, opposite end thereof; a feedthrough insulator residing in the ferrule opening and having an outer sidewall hermetically sealed to an inner surface of the ferrule sidewall, the feedthrough insulator comprising at least one feedthrough insulator bore for passage of at least one electrically conductive terminal pin there through; and a terminal pin hermetically sealed in the feedthrough insulator bore; b) providing a filter capacitor, comprising the steps of: c) mounting the filter capacitor on at least one outer side of the feedthrough insulator; and d) electrically connecting the first active electrode layer to the terminal pin and the second ground electrode layer to the ferrule.
