Abstract
The capacitor according to the invention is wound from at least one film ( ) comprising a carrier film ( )—serving as dielectric—with at least one conductor layer ( ). It has an internal series circuit. The latter is brought about by the conductor layer ( ) applied on the dielectric or the conductor layers being divided into sectors ( ) which are mutually arranged and, if appropriate, connected to one another in such a way that a plurality of series-connected elementary capacitors are formed. It is distinguished essentially by the fact that a current path structure is formed on the sectors, the conductor layer ( ) having a high sheet resistance for the purpose of reducing breakdown-governed capacitance losses and the current paths ( ) of the current path structure having a significantly reduced sheet resistance for the purpose of reducing the total sheet resistance.
