Abstract
An electrical capacitor is formed utilizing a thin dielectric layer which is metallized on both sides to provide electrode areas. Unmetallized margin areas are provided on one side of the dielectric layer along the longitudinal edges of the layer, an unmetallized strip is provided in the center of the other side of the dielectric area which extends along the longitudinal dimension of the layer. The capacitor is formed by pleating, or folding, the dielectric layer once along its longitudinal dimension in the unmetallized central strip area slightly off of the center line of the dielectric layer, so that the unmetallized strip is on the inside of the pleat. The ends of the metallized dielectric layer which contain the unmetallized margin areas are thus staggered so that one end extends beyond the other.
