Abstract

Multiple capacitors wound from two thin metallized dielectric films on a common core are provided with electrostatic shielding therebetween. A first capacitor is wound in the usual manner using two metallized films. After the winding of the first capacitor, the metallized layers are removed from the first and second metallized films over predetermined intermediate regions of the films. A film of insulating material and a metal shielding layer are then wound between the first and second films with the insulating material and the metal shielding layer extending outwardly from one end of the cylindrical form. The film of insulating material and the metal shielding layer are wound to encircle the capacitor at least once, with the film of insulation material encircling the metal shielding layer on each side thereof. After the metal shielding layer has been wound, the winding of the first and second metallized films is completed to form a second capacitor on the first capacitor. The ends of the capacitors so wound are metal coated and electrical connections are made to the first and second capacitors on the coated ends thereof. An electrical connection is also made to the shielding layer within the barrier formed by the film of insulation material.
