Series wound capacitive structure

A capacitor having opposed first and second metallic films separated by a dielectric. The first metallic film includes a first relatively narrow metal-free zone spaced from an edge thereof so as to form a first marginal metal film band at an edge which is spaced by the first metal-free zone from the remainder of the first metallic film. The first metallic film further includes a first metal-free margin lane arranged between the metal-free zone and an edge thereof to separate the first metallic film into first and second segments. The second metallic film includes a second relatively narrow metal-free zone spaced from an edge thereof so as to form a second marginal metal film band at an edge which is spaced by the second metal-free zone from the remainder of the second metallic film. The second metallic film further includes a second metal-free margin lane arranged between the second metal-free zone and an edge thereof to separate the second metallic film into third and fourth segments.
