Abstract
Capacitor comprising a first metallized film electrode, a second metallized film electrode capacitively coupled to, and longer than, the first metallized film electrode, each metallized film electrode having an electrically non-conducting plastic substrate with a metal coating, a metal foil electrode capacitively coupled to the second metallized film electrode in the zone beyond the end of the first metallized film electrode, a first plastic film intermediate the metal foil electrode and the second metallized film electrode, each of its ends extending beyond each end of the metal foil electrode to prevent the edges of the metal foil electrode from penetrating the plastic substrate of the second metallized film electrode, and a second plastic film adjacent to the metal foil electrode on the side opposite the first plastic film to insulate the metal foil electrode from the metal coating.
