Abstract
Abstract A high capacitance bus bar including at least two separated conductive plates between which a plurality of capacitive ceramic dielectric chips are positioned and adhered. Opposite faces of the chips are coated with a thin, integral and continuous film of conductive material and the coated chips are adhered to the conductive plates with a conductive adhesive.
