Abstract: A rolled metallized film capacitor is encased between a pair of box halves (13 and 13') each having a pair of dovetailed slots (36 and 37) formed in opposite walls so that when the box halves are assembled about a capacitor blank (10) the slots in the respective box halves are aligned with each other. The box halves are mounted in abutting relation about a pair of parallel wires (11 and 12), and then heat fusible metal (46 and 47) is deposited in the aligned slots to lock the box halves together while bonding the wires (11 and 12) to opposite ends of the capacitor blank (10). When assembled, the boxed capacitor with the laterally extending leads may be readily machine inserted or otherwise assembled in a circuit module, such as a printed circuit board.

Abstract: A rolled metallized film capacitor is manufactured by completely metallized one surface of each of a pair of dielectric films, and advancing the films while laser scribing patterns of demetallized lines on the respective films which are wound together to provide a pair of capacitor plates of finite areas. As the films are advanced the laser scribing is controlled so that when the films are wound together, the lines on the respective films are in overlaying relationship on the core and peripheral windings, and are diverted to opposed marginal edge portions of the respective films on the intervening windings. When the rolled capacitor films are terminated and connected to a power source the opposed metallized areas on the core and peripheral windings are subjected to equal potentials, whereas the remainder of the windings present two metallized areas between the opposed margin lines which are subjected to potential of opposite polarity to accumulate charges and function as capacitor plates.

Abstract: A wound resistor-capacitor network having stable frequency response over a wide frequency range (e.g., 60 cycles to 100 kilohertz), is produced by forming a pair of aligned circumferentially extending resistance paths in one of two strips of metallized dielectric film. Forming of the resistance paths is accomplished as the two metallized strips are being wound to form an R-C network roll, by removing metal from the one strip along a first line to produce a gap in the metal layer in parallel spaced relationship to an adjacent edge of the film. Subsequently, removal of metal from the first strip also is initiated along a second line spaced inward from the first line, to produce another gap in the metal layer, thereby forming an elongated first path of desired resistance between the two lines. Metal removal along the first line then is temporarily interrupted to provide a lead termination area and a current steering path at the adjacent end of the network roll, on either side of the strip midpoint.
