Abstract
A rolled film capacitor comprising a pair of dielectric film strips piled one upon another and wound into a roll, each strip having a metal electrode pattern deposited on one surface thereof, the pattern including a number of rectangular island electrodes mutually separated by a plurality of lateral and longitudinal insulating gaps and regularly arrayed in both directions, the island electrodes mutually overlapping to form a number of small capacitor elements which are connected in series in both directions by shifting both strips one from another in both directions. A plurality of such capacitors can be aggregated to form an improved large capacitive power supply device.
