Patent ID: 8855768

Claim:
An RF capacitor, comprising: a) a dielectric body comprising a dielectric sidewall extending along a longitudinal axis from a dielectric body first end to a dielectric body second end; b) a terminal member supported in the dielectric body and comprising a length extending to first and second terminal ends spaced from the respective first and second dielectric body ends; c) a plurality of active electrode plates supported in the dielectric body, each active electrode plate having an active electrode length extending from a first active edge to a second active edge electrically connected to the terminal member, d) a plurality of ground electrode plates supported in the dielectric body, each ground electrode plate having a ground electrode length extending from a first ground edge to a second ground edge electrically connectable to an energy dissipating surface comprising a conductive ferrule or an active implantable medical device (AIMD) housing, e) wherein the ground and active electrode plates are in an interleaved, spaced relationship with only a portion of the active and ground electrode lengths extending from the first active and ground edges to the respective second active and ground edges being vertically above or below the other of the active and ground electrode plates in an orientation extending along the longitudinal axis of the dielectric body; and f) at least three extra ground electrode plates in the dielectric body, each extra ground electrode plate extending from an extra ground electrode plate first edge electrically connectable to the energy dissipating surface to an extra ground electrode plate second edge spaced from the terminal member and being in a spaced relationship with the plurality of interleaved active and ground electrode plates along the longitudinal axis without any active electrode plates being interleaved between the three extra ground electrode plates.
