摘要
A filter feedthrough is described. The filter feedthrough includes a conductive ferrule supporting a dielectric substrate having a body fluid side and a device side. At least one via hole provided with a conductive fill is disposed through the dielectric substrate from the body fluid side to the device side. At least one MLCC-type capacitor is supported by the dielectric substrate. A first circuit trace couples from an active metallization connected to the active electrode plates of the capacitor to conductive fill in the via hole. A second circuit trace couples from the ground electrode plate of the capacitor to a metallization contacting an outer surface of the dielectric substrate. Then, a conductive material couples from the ground metallization to the ferrule to thereby electrically couple the capacitor to the ferrule.
