Abstract: A capacitor module includes a first capacitor and a second capacitor, the first capacitor and the second capacitor each including a first electric terminal and a second electric terminal, a conductor to connect corresponding first electric terminals of the first capacitor and the second capacitor, and a connector to connect the conductor to corresponding second electric terminals of the first capacitor and the second capacitor.

Abstract: A capacitor module (1) is proposed, in which a first (10A) and a second capacitor (10B) are located, in each instance, in separate, metallically conductive housings (5A, 5B) that are tightly sealed from one another. The two housings are connected with one another by way of a contact surface, wherein an internal electrical circuit comes about. Each housing has at least one first connector (2A, 2B) that is electrically insulated from the housing, in each instance. Because of the direct electrical connection between the two capacitors, a capacitor module according to the invention requires fewer screw connections and thereby can be produced in simpler and more cost-advantageous manner.

Abstract: A capacitor winding for a capacitor has a layer stack that is limited by two end faces in a longitudinal direction and by one or more lateral surfaces that extend transverse to the longitudinal direction. The stack has electrode layers and parting layers proceeding in the longitudinal direction, and has a single-ply sheath of an electrically insulating material that covers the lateral surfaces of the layer stack gap-free and that has a projecting section at an end face. The sheath can be especially advantageously implemented as a heat shrinkable tube or hose that protects the capacitor winding against damage upon insertion into a housing of the capacitor.

Abstract: The invention is directed to a capacitor winding (9) having a layer stack (1) that is limited by two end faces (2) in a longitudinal direction and by one or more lateral surfaces (3) transverse to the longitudinal direction, comprises electrode layers (4) and parting layers (5) proceeding in longitudinal direction, and having a single-ply sheath (6) of electrically insulating material that covers the lateral surfaces (3) of the layer stack (1) gap-free and that comprises a projecting section (7) at an end face (2). The invention is also directed to a capacitor having the capacitor winding (9). The sheath (6) can be especially advantageously implemented as shrink hose that protects the capacitor winding (9) against damage upon insertion into a housing (10).

Abstract: A circuit arrangement comprises a chain (1) composed of double layer capacitors (2). Modules (3) whose impedance lowers when the voltage across one of the double layer capacitors (2) exceeds a prescribed value are connected parallel to the double layer capacitors (2). As a result thereof, over-voltages at the double layer capacitors (2) are effectively suppressed.
