ABSTRACT:
Filtered feedthrough assembly (100, 200) is formed by mounting a filter support assembly (130, 130', 230) having a capacitor (110,210) mounted thereto, to a conductive feedthrough (10, 10'). The conductive feedthrough includes a metallic ferrule (14, 14') having a centrally disposed through opening (28) extending between opposing ends thereof. At least one elongate lead wire (12) extends through the ferrule through opening. A hermetic seal insulator (20, 20') is disposed within the central opening of the ferrule and is sealed thereto. The filter support assembly (130, 130', 230) includes an insulative substrate (132, 132', 132") having a first metallization pattern (133, 314) formed on an upper surface (138, 138") thereof. A second metallization pattern (135, 316) is formed on the lower surface (124, 124') of substrate (132, 132', 132"). A capacitive element (110, 210) is electrically coupled between a first metallization area (145, 318) and second metallization area (143,320) of the first metallization pattern (133, 314). The first metallization area (145, 318) is electrically coupled to the lead (12) and the second metallization area (143, 320) is electrically coupled to the ferrule (14, 14'). The second metallization area (145, 318) includes a metallized recess (140, 140') formed in a perimeter edge (134, 134') of the substrate (132, 132', 132"). A conductive contact material (150) is disposed within the recess for providing the electrical connection to the ferrule (14, 14'). A conductive contact material (152) provides the electrical connection between the lead (12) and the first metallization area (145, 318).
