ABSTRACT:
A metallized capacitor has two layers of electrically insulating film wound as a roll, two metal electrodes vacuum deposited on respective ones of the two layers of film, and two end-sprays of electrically conductive material deposited on respective ends of the roll, each of the end-sprays being in electrical contact with one of the two vacuum-deposited metal electrodes. Each of the metal electrodes has a segmented metallization pattern having segments of relatively thick electrode material separated by periodic segments of relatively thin electrode material so as to define a repeating pattern of relatively thick and relatively thin segments along the length of the layer of electrically insulating film on which the metal electrode is deposited. Each of the metal electrodes may have a thickness, at at least certain locations along the length of the film on which the electrode is deposited, that decreases from the end-spray with which the metal electrode is in contact to an edge of the film that is opposite to the end-spray, the thickness having a profile from the end-spray to the edge opposite the end-spray that provides approximately constant wattage from a point in the vicinity of the end-spray to a point in the vicinity of the edge opposite the end-spray during use of the capacitor.
