Abstract
A solid electrolytic capacitor has an anode which consists of a sintered tantalum member having a dielectrically effective oxide layer located thereon and a counterelectrode consisting of semiconducting manganese dioxide. An anode wire is coated with polytetrafluorethylene in the vicinity of the point it enters the sintered member. In a method for producing such an electrolytic capacitor, the anode wire is brushed with a suspension containing the polytetrafluorethylene in a solvent in the vicinity of the wire entry point, before the manganese dioxide layer is produced, and the suspension is burnt-in for annealed after such application, where annealing occurs at a temperature of approximately 300.degree. C. over a period of time of approximately ten minutes.
