Patent number: 6909595Abstract: 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.Type: GrantFiled: July 25, 2001Date of Patent: June 21, 2005Assignee: EPCOS AGInventors: Werner Erhardt, Bernd Staib

Patent number: 6740351Abstract: For manufacturing a multi-layer structure with repeating layer sequences, a band-shaped carrier material is first partially separated into individual sections of a same size with connections capable of bearing remaining between the individual sections. After continuously applying at least one further material layer on the surface of the carrier material, the individual sections are completely separated by cutting or punching. The multi-layer structure is obtained by stacking the individual sections obtained in this way on top of one another, whereby intermediate layers can also be potentially inserted between two individual sections.Type: GrantFiled: June 20, 2002Date of Patent: May 25, 2004Assignee: Epcos AGInventors: Klaus Schoch, Werner Erhardt, Hartmut Michel

Publication number: 20040027782Abstract: The invention relates to an electrical double layer capacitor with two superimposed electrode layers (2, 3). These electrode layers (2, 3) are separated by an electrically insulating dividing layer (1). At least one of the electrode layers (2, 3) is applied to the dividing layer (1) by means of a coating process. The advantage of the capacitor of the invention is that the dividing layer (1) coated by the electrode layer (2, 3) allows for improved volume utilization.Type: ApplicationFiled: June 4, 2003Publication date: February 12, 2004Inventors: Werner Erhardt, Christoph Weber
