Abstract

An aluminum electrolyte capacitor is composed of a capacitor winding, of an anode foil provided with a dielectrically effective barrier layer, having spacers (1), particularly of paper, saturated with an operating electrolyte, and of a cathode foil, and is built into a housing. The spacers have an impressed line structure (2) that is arranged from one face end of the capacitor winding to the opposite end face.
