Claim:
A capacitor, comprising: (a) a metal case, having an open side; (b) a capacitor element positioned inside the case; (c) an electrolyte solution contained in the case and in contact with the capacitor element; (d) a lid comprising i. a unitary metal plate bonded to the open side of the case, the plate having an outer side, an underside, and a hole extending through its thickness from the outer side to the underside; ii. a chamber defined by an outer metal-glass-inner metal hermetic seal covering a side of the hole adjacent the outer side of the plate, wherein the outer metal component of the hermetic seal is bonded to the plate, a liquid seal affixed to the plate and covering a side of the hole adjacent the underside of the plate, wherein the liquid seal has a metal terminal, and the terminal is electrically insulated from the plate by an elastomeric ring positioned between the terminal and the plate, and side walls, wherein the side walls of the chamber are portions of the plate defining the hole; (e) a first electrical connection between the capacitor element and the terminal; and (f) a second electrical connection between the terminal and the inner metal component of the hermetic seal.
