Abstract
A power terminal feed-through includes a housing body, a plurality of conductive pins, and a seal structure that hermetically seals the conductive pins to the housing body and electrically insulates the conductive pins from the housing body. The seal structure includes a first material fused to one of the housing body and the conductive pin, and a second material fused to the other one of the housing body and the conductive pin. The first and second materials may be properly chosen to match thermal expansion of the housing body and the conductive pins, respectively.
