Abstract
A capacitor having an anode of a pressed powder pellet is described. The pressed powder anode pellet has a contoured trough that extends inwardly into the height of the pellet from a peripheral edge of the pellet. A shaped anode wire has an embedded portion residing inside the pellet and an outwardly extending portion that is connected to the terminal pin of a feedthrough. The feedthrough is nested in the contoured trough. In order to prevent a crack from rendering the anode inoperable, the embedded portion of the anode wire is shaped to bridge the lateral extent of the contoured trough. Should a crack develop in the anode, the crack will intersect the embedded portion of the anode wire. As an embedded bridging wire structure, the crack in the anode pellet will not cause the shaped anode wire to break. Instead, the shaped anode wire provides electrical continuity from one side of the crack to the other so that the capacitor remains functional.
