Abstract: The disclosure concerns the fabrication of film capacitors of the stacked or coiled type. These capacitors, shaped like a block, are made with films supporting at least one metallization. They have two metal plates placed on two opposite lateral faces of the block. These plates are formed by at least two pads. One of the pads of each plate is used to apply a severe electrical treatment. These pads are obtained by making a notch in the plate or by masking during the metallization of the plate. The disclosure is applicable to film capacitors capable of undergoing a severe electrical treatment without loss of capacitance.

Abstract: Metallized dielectric film is employed to manufacture capacitors. In order to attach a certain number of inactive layers to the capacitors, the method comprises a stage which consists in displacing the layers laterally during the winding operation in order to obtain a determined thickness of inactive layers, the lateral displacement causing the prevention of the connection of the metallizations of the films to the lateral Schoop coatings.
