  • Patent number: 6920673
    Abstract: A feedthrough device and brazing process for joining the constituent parts of the feedthrough while allowing a lead to pass therethrough in a nonconductive manner is described. The feedthrough comprises at least one lead, a ferrule defining a capacitor recess and an insulator recess. An insulator disposed in the insulator recess defines a passageway allowing the lead to pass therethrough. A capacitor disposed in the capacitor recess defines a capacitor passageway allowing the lead to pass therethrough. The capacitor comprises first and second sets of plates, the first set being conductively coupled to the ferrule and the second set being conductively coupled to the lead. The braze joints between the insulator and the lead and between the insulator and ferrule are formed first at a first temperature using an insulator braze material.

  • Patent number: 6768629
    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.

  • Publication number: 20030123215
    Abstract: A feedthrough device and brazing process for joining the constituent parts of the feedthrough device, while allowing a lead to pass therethrough in a nonconductive manner. The feedthrough comprises at least one lead, a ferrule defining a capacitor recess and defining an insulator recess, an insulator disposed in the insulator recess of the ferrule, the insulator defining a passageway sized to allow the lead to pass therethrough. The feedthrough further comprises a capacitor disposed in the capacitor recess and defining a capacitor passageway sized to allow the lead to pass threrethrough, and the capacitor comprises first and second sets of plates, wherein the first set of plates is conductively coupled to the ferrule and the second set of plates is conductively coupled to the lead. Brazing is a two step process wherein the braze joints between the insulator and the lead and between the insulator and ferrule are formed first at a first temperature using an insulator braze material.

  • Patent number: 5440447
    Abstract: An electronic feed-through system that is adapted for use in situations in which the feed-through is bonded to a container or the like by a process that subjects the feed-through system to heating. The feed-through system includes an electrically conductive structure adapted to be attached to a second structure at a first location on the conductive structure. The conductive structure has an electrically conducting member connected to the first location. A portion of the conductive structure is subjected to heat during said attachment. The feed-through system also includes an electronic component such as a feed-through capacitor. The electronic component requires electrical connection to the conducting member and placement in proximate spaced relation to the conducting member. An electrically conducting thermally resistant bridge is used to connect the electronic component to the conducting member and maintain the component in the spaced relationship with the member.
