摘要：
A hermetically sealed filtered feedthrough includes a chip capacitor disposed on a circuit board on a device side. A first low impedance electrical connection is between a capacitor first end metallization and a conductor which is disposed through an insulator. A second low impedance electrical connection is between the capacitor second end metallization and a ferrule or housing. The second low impedance electrical connection may include an oxide-resistant electrical connection forming the hermetic seal between the insulator and the ferrule or housing and an electrical connection between and to the second end metallization and directly to the oxide-resistant electrical connection. Alternatively, the second low impedance electrical connection may include an oxide-resistant metal addition attached directly to the ferrule or housing and an electrical connection between and to the second end metallization and directly to the oxide-resistant metal addition.
