Abstract
A filtered feedthrough comprises an insulator sealed in a ferrule opening. A terminal pin sealed in an insulator via hole has a first end that extends outwardly beyond an insulator device side. A filter capacitor has a square- or rectangularly-shaped dielectric supporting interleaved active and ground electrode plates. A passageway extending through the dielectric has an internal metallization. An external metallization is contacted to opposed longitudinal sides of the dielectric outer surface. The capacitor ground electrode plates extend to the opposed external metallizations.…
