Abstract
A filtered feedthrough including a ferrule surrounding an insulator supporting one or more lead wires and at least one ground pin is described. The insulator defines a channel cutout extending from a first insulator side to a channel cutout bottom part way through the thickness of the insulator and in communication with the ferrule. An attached filter capacitor shunts electromagnetic interference from the lead wire to the ground pin, and the ground pin is in electrical communication with the ferrule by way of a ferrule-ground pin braze joint formed in the channel cutout.
