Abstract
A regenerable electric capacitor having wound-on layers of plastic foils provided with metal layers of the coatings. The metal layers consist of an alloy and include a variable thickness perpendicular to the longitudinal direction of the foils. As such, the thickness of the metal layers is smallest in the regions bordering metal-free edge strips and it increases towards the opposite side of the foil. In addition, the metal layers have an alloy composition that is different dependent transverse to the direction of run of the foils.
