Patent number: 5614111Abstract: A metallized film capacitor in which the metallization is made as thin as possible in order to increase the dielectric strength of the film. In the industry, typical metallization thicknesses range from approximately 1-4 ohms/sq, however, the present invention employs thicknesses which range from 5-300 ohms/sq.

Patent number: 5371650Abstract: A hermetically sealed capacitor including a metal tape (e.g, copper) having an adhesive on one side and being folded and wrapped around the capacitor winding in the manner that a Christmas package is wrapped. After wrapping, the tape initially extends beyond both ends of the capacitor. The tape is then folded at one end of the capacitor. The seam of the tape overlapping itself (along the length of the capacitor) and the fold at the one end of the capacitor are each soldered. On the other end of the capacitor, a ceramic header having a through hole (for one of the capacitor leads) is positioned. The tape extends beyond the ceramic header and is folded so as to make contact with the ceramic header. The seam between the metal tape and the ceramic piece is then soldered. In this way, a small, hermetically sealed capacitor is obtained.Type: GrantFiled: February 15, 1994Date of Patent: December 6, 1994Assignee: Electronic Concepts, Inc.Inventor: Bernard Lavene

Patent number: 4547832Abstract: A method is disclosed for making a wound capacitor having decreased inherent inductance and a high self-resonant frequency. In making this capacitor, metallized film is wound around a non-conductive polycarbonate core and a conductor is inserted through the entire length of the core. The wound metallized film is flattened and terminals are formed at opposite ends of the flattened wound capacitor. The conductor is folded over and electrically connected to one terminal and a metal contact is electrically connected to the other terminal. The electromagnetic field created around the conductor is approximately equal and in the opposite direction to the electromagnetic field created around the wound metallized film. Therefore, the inductive reactance of the conductor and the inductive reactance of the wound film are approximately equal. These reactances approximately cancel resulting in increased self-resonant frequency.Type: GrantFiled: March 5, 1984Date of Patent: October 15, 1985Assignee: Electronic Concepts, Inc.Inventor: Bernard Lavene
