摘要:
A hermetically sealed filtered feedthrough assembly attachable to an AIMD includes an insulator hermetically sealing the opening of a ferrule with a gold braze. The ferrule includes a peninsula extending into the ferrule opening and the insulator has a cutout matching the peninsula. A sintered platinum-containing paste hermetically seals at least one via hole extending through the insulator. At least one capacitor is disposed on the device side. An active electrical connection electrically connects the capacitor active metallization to the sintered paste. A ground electrical connection electrically connects the capacitor ground metallization disposed within a capacitor ground passageway to the portion of the gold braze along the ferrule peninsula. The dielectric of the capacitor may be less than 1,000 k.
