A multipolar feedthrough filter capacitor assembly for an active implantable medical device includes a feedthrough filter capacitor including a first active electrode plate, a second active electrode plate and a plurality of ground electrode plates. The plates are in spaced parallel relation disposed within a monolithic dielectric substrate where the first and second active electrode plates are disposed between the plurality of ground electrode plates. A first conductive terminal pin is disposed through the feedthrough filter capacitor electrically coupled to the first active electrode plate and in non-conductive relation to both the second active electrode plate and ground electrode plate. A second conductive terminal pin may be disposed through the feedthrough filter capacitor electrically coupled to the second active electrode plate and in non-conductive relation to both the first active electrode plate and ground electrode plate.
