A DC link capacitor includes a plurality of wound capacitors, each having a first connection pole and a second connection pole, a first current-tapping element by which the first connection poles are contacted, and a second current-tapping element by which the second connection poles are contacted. First wound capacitors, of the plurality of wound capacitors, are arranged in a first row and oriented such that the first connection poles are arranged on a first side of the DC link capacitor and the second connection poles are arranged on a second side of the DC link capacitor. Second wound capacitors of the plurality of wound capacitors are arranged in a second row, where the first and second rows are arranged parallel to each other in a common plane, and where the second wound capacitors are oriented such that the first connection poles are arranged on the second side of the DC link capacitor and the second connection poles are arranged on the first side of the DC link capacitor.

A capacitor has an anode with one or more active layers that each includes fused particles positioned on a current collector. The current collector includes tunnels that extend from a first face of the current collector to a second face of the current collector.

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.

A capacitor carrier assembly includes a carrier, a capacitor disposed in the carrier and electrically conductive connection terminals. The connection terminals support the carrier with respect to another electronic component or device such as a printed circuit board, retain individual carrier portions in an assembled configuration, and provide an electrical connection between the capacitor and the electronic component. Each connection terminal includes an elastic member that protrudes from a surface of the connection terminal and engages the carrier, and regions of serrations provided on opposed edges of the terminal that engage the carrier, and a flange that protrudes from the surface in a direction perpendicular to the first surface. An edge of the flange includes an insulation displacement contact (IDC) joint for connection to the capacitor leads.
