PLEATED METALLIZED FILM CAPACITOR WITH STAGGERED EDGES Abstract of the Disclosure An electrical capacitor is formed utilizing a thin dielectric layer which is metallized on both sides to provide electrode areas. The capacitor is formed by pleating, or folding, the dielectric layer along its longitudinal dimension an odd number of times. The pleats are not creased but are allowed to form smoothly curved edges in which the radius of such bend is at least equal to the thickness of the film. In addition the edges of the pleats are progressively staggered so that the centers of the bend of one pleat edge is removed a distance of at least four film thicknesses from its neighboring centers. This configuration prevents the end of the capacitor from forming a "bar-bell" shape and in addition minimizes mechanical damage to the film and alternation of the electric field.
