Abstract

An internally grounded filter feedthrough having a filter capacitor connected to a feedthrough is described. The feedthrough comprises an insulator having an active conductive pathway extending to its device and body fluid sides, and a ground conductive pathway extending part-way through the insulator thickness from the insulator device side. An undercut extending into the insulator sidewall communicates with the ground conductive pathway but does not extend to the insulator device or body fluid sides or to the active conductive pathway. A braze seals the insulator sidewall to the ferrule and extends into the undercut so that the braze contacts the ground conductive pathway. That way, the braze provides a ground electrical path from a capacitor ground via to the ground conductive pathway in the insulator connected to the braze sealed to the ferrule.
