Abstract

An exemplary capacitor has a capacitor stack positioned in a case with a conductor positioned between the case and a lid. In one embodiment the conductor is positioned between the lid and an upper rim of the case and is welded to the lid and case. In one aspect, a capacitor constructed with round wire connectors for interconnecting anode and cathode layers. In one aspect, a configuration for electrically connecting a terminal wire to a capacitor case in which an end of the wire is attached to the case in end-on fashion. The terminal wire may have an expanded end for attaching to the capacitor case in a manner that minimizes the effect on the height profile of the case.
