Abstract
Abstract A capacitor unit incorporating at least two capacitor sections and comprising a strip of dielectric material having a metallized layer electrode thereon extending to one edge of said strip of dielectric material and being spaced from the other edge of said strip of dielectric material, a second strip of dielectric material extending the length of said first strip and positioned against said metallized layer and a plurality of longitudinally spaced strips of metal foil defining a corresponding plurality of electrodes to each of which a terminal tab is secured, the various strips and electrodes being wound into a coil and with the end of the coil at which the edges of the convolutions of the metallized electrode is exposed, being metallized and having a terminal tab connected to said metallized end.
