1. A capacitor assembly, comprising:
- a substantially monolithic casing of dielectric material having a plurality of conductive active and ground electrode plates encased therein in an alternating stack and in predetermined spaced relation;
each of said active and ground electrode plates comprising a pair of closely spaced conductive plate elements of the same length and separated by a thin layer of dielectric material to preserve the capability of the capacitor assembly to reliably withstand inrush currents from voltage pulses and surges.

Abstract
An improved capacitor is provided particularly for use in electromagnetic interference (EMI) filter applications, for example, in an implantable medical device such as a heart pacemaker or defibrillator, to accommodate relatively high pulse currents. The capacitor comprises a plurality of active and ground electrode plates interleaved and embedded within a dielectric casing of ceramic or the like with each active and ground plate being defined by a closely spaced pair of conductive plate elements which significantly increase the total area of each electrode plate, and thereby correspondingly increase the current handling capacity of the capacitor.
