ABSTRACT:
A capacitive structure, which structure is a length of a plurality of layers, each layer having opposed edges and comprising a dielectric substrate and a metallic film. The metallic film extends from one edge toward the other edge. Each layer includes a zone free of metallic film, which zone is spaced from the other edge and defines a narrow marginal metal film band at the other edge which is spaced from the remainder of the metallic film by the metal free zones. The layers are disposed with the metallic film of each layer being separated by dielectric material from the metallic film of the adjacent layer; the layers are offset such that first edges of a first group of layers lie outwardly beyond second edges of a second group of layers at one side of the structure, and first edges of the second group of layers lie outwardly beyond the second edge of the first group of layers at the other side of the structure, the layers of the first group alternating with the layers of the second group. The layers of each group are coated with electrically conductive material to electrically connect the metallic film of each layer of each respective group.
