ENERGY STORAGE QUICK DISCHARGE CAPACITOR

PURPOSE:To raise a working potential gradient and miniaturize a capacitor by forming a small-capacity metallized film or metallized paper into many series connections and parallel connections, by reducing a breakdown discharge energy in the defective part of the film or insulating paper, and by limiting the amount of evaporation and scattering of a deposited metal through the discharge of that part. CONSTITUTION:Two films a, b having a metal-deposited electrode on one surface are piled up into capacitor elements. A deposited metal part is provided with insulating parts 2, 2' continuing in the longitudinal direction and three or more series capacitors are formed in one capacitor element. Insulating parts 3, 3' are also provided in the width direction of a film and a capacity in one capacitor element is divided into many parallel connections. Out of many small capacitors formed into a plurality of capacitor parallel circuits in that element, input-output terminal lead-out parts 1, 1' in contact with metal sputter are continuous or a plurality of continuous conductors. Therefore, even if e.g. a small capacitor C1 part is defective to cause a dielectric breakdown, other parts are not influenced by the breakdown.
