Abstract

A capacitor structure comprises a shallow drawn encasement having first and second major sides and a peripheral wall coupled to the first and second sides. A cathode is disposed within the encasement proximate the first and second major sides, the cathode having a cathode lead. A central anode a having an anode lead is disposed within the encasement, and a bipolar, insulative feedthrough extends through the encasement through which electrical coupling may be made to the anode lead and the cathode lead.
