EMI feedthrough filter terminal assembly includes a feedthrough filter capacitor
having first and second sets of electrode plates, and a first passageway having
a first termination surface conductively coupling the first set of electrode plates.
At least one lead wire extends through the first passageway and is conductively
attached to a first oxide resistant conductive pad. The first pad is conductively
coupled to the first termination surface independently of the lead wire. The terminal
assembly may also include a conductive ferrule through which the lead wire passes
in non-conductive relation, and an insulator fixed to the ferrule for conductively
isolating the lead wire from the ferrule. The ferrule and insulator form a pre-fabricated
hermetic terminal pin sub-assembly. The capacitor may include a second passageway
having a second termination surface conductively coupling the second set of electrode
plates, and a conductive ground lead extending therethrough.
