Title: Film capacitor
Inventor: TASAKA AKIHIRO
IPC: H01G4/18
Filed: 1988-05-25
Abstract: PURPOSE:To suppress generation of strain voltage, by winding or laminating metallized films which form stratified electrodes at the both sides of dielectric films as well as the electrodes which are disposed between the films. CONSTITUTION:Electrodes 3 and 4, 5 and 6 are formed at the both sides of dielectric films 1 and 2 with a vaporization process. Electrodes 7 and 8 consisting of metallic foils are wound in such a way that an electrode 7 is located between electrodes 4 and 5; besides, an electrode 8 is located between 6 and 3 when the electrode 8 is wound. As the electrodes 3 and 4, 5 and 6 are disposed on the films 1 and 2, sucking and repelling forces from the outside are not applied to the films 1 and 2 and then, these films do not cause oscillations according to input signals. Strain voltage which takes places between capacitors thus decreases.
