Patent ID: 8098479

Claim:
A capacitor, comprising: (a) a capacitor element having a first set of conductive plates and a second set of conductive plates, wherein the plates in the first set of plates and the plates in the second set of plates are arranged in alternating layers, separated by a dielectric, and wherein the first set of plates and the second set of plates are staggered relative to each other to create a first common edge for the first set of plates and a second common edge for the second set of plates; (b) a first metal coating applied to the first common edge of the capacitor element and a second metal coating applied to the second common edge of the capacitor element, wherein the first and second coatings are applied by thermal spraying, and wherein the first and second coatings are selected from the group consisting of zinc and zinc rich alloys; and (c) a first metal terminal welded to the first coating to form a metallurgical bond, wherein the first metal terminal is selected from the group consisting of aluminum and aluminum rich alloys, and a second metal terminal connected to the second coating.
