Abstract: The present invention is a multi-section capacitor which includes a plurality of capacitor sections. Each of the plurality of capacitor sections has a right end and a left end and is wound from a length of a first metallized dielectric film having disposed on its near surface a first thin metallized layer which extends to its right edge but terminates short of its left edge leaving a non-metallized strip therealong in combination with a length of a second metallized dielectric film having disposed on its near surface a second thin metallized layer which extends to its left edge but terminates short of its right edge leaving a non-metallized strip therealong so that the first and second thin metallized layers are separated by dielectric film. A portion of the first thin metallized layer is removed at a region intermediate the ends of the length for a distance sufficient to encircle the capacitor section at least once.

Abstract: The present invention is a combination of a laser system and a controller for use in vaporizing the material of a metallized dielectric film capacitor to form a hole in order to trim its capacitance. The combination includes a laser system which has a laser modulator, a mechanical triggering device and a controller which includes a trigger/reset circuit which is electrically coupled to the mechanical triggering circuit and which provides a trigger signal in its triggered state and a reset signal in its untriggered state. The controller also includes a clock circuit which is electrically coupled to the trigger reset circuit and which provides clock signals in response to the trigger signal and a one-shot monostable, multivibrator circuit having an RC timing circuit which is electrically coupled to the clock circuit and to the laser modulator and which controls the pulse width of its output signal in response to the clock signals.
