1. An EMI feedthrough filter terminal assembly, comprising:

  • a feedthrough filter capacitor including first and second sets of electrode plates, a passageway therethrough having a first termination surface conductively coupling the first set of electrode plates, and a second termination surface exteriorly coupling the second set of electrode plates;

    a conductive ferrule adjacent to the feedthrough filter capacitor;

    at least one conductive terminal pin extending through the passageway in conductive relation with the first set of electrode plates, and through the ferrule in non-conductive relation;

    an insulator fixed to the ferrule for conductively isolating the terminal pin from the ferrule; and

    an oxide resistant conductive hermetic seal between the insulator and the ferrule, the oxide resistant conductive seal including an oxide resistant conductive pad on a surface of the ferrule conductively coupled to the second termination surface.
