Patent ID: 7564674

Claim:
A feedthrough assembly, which comprises: a) an insulator of electrically non-conductive material having a height defined by an insulator sidewall extending to a first insulator end and a second insulator end, wherein the insulator has at least one terminal pin bore extending from the first end to the second end thereof; b) a terminal pin received in the terminal pin bore, the terminal pin having a sidewall extending to opposed first and second ends disposed spaced from the respective first and second insulator ends, wherein the terminal pin comprises a terminal pin core of a first electrically conductive material other than palladium and an outer layer of palladium provided as a continuous coating supported on the terminal pin core; c) a ferrule of an electrically conductive material and comprising a ferrule opening defined by a surrounding sidewall extending to a first ferrule end and a second ferrule end, wherein the insulator is supported in the ferrule opening; and d) a first braze material contacting the palladium coating on the terminal pin core thereby hermetically sealing the terminal pin to the insulator and a second braze material hermetically sealing the insulator to the ferrule.
