20100039748 | CASE-MOLDED CAPACITOR AND METHOD FOR USING THE SAME - In a case-molded capacitor, an electrode of a capacitor element is connected with a busbar having an electrode terminal for external connection. The capacitor element and the busbar are placed in a metal case having an upper surface opening and are resin molded. A thermally-conductive insulator layer is provided between the capacitor element and a bottom surface of the metal case, hence providing the case-molded capacitor with a heat resistance. | 02-18-2010 |
20110090618 | METALIZED FILM CAPACITOR - A metalized film capacitor includes a first dielectric film, a first metal thin-film electrode provided on a surface of the first dielectric film, a second dielectric film provided on the first metal thin-film electrode, and a second metal thin-film electrode provided on the second dielectric film, such that the second metal thin-film electrode faces the first metal thin-film electrode across the second dielectric film. The surface of the first dielectric film has a surface energy ranging from 25 mN/m to 40 mN/m. The metalized film capacitor exhibits high heat resistance and a preferable self-healing effect. | 04-21-2011 |
20110102966 | MOLDED CAPACITOR AND METHOD FOR MANUFACTURING THE SAME - A molded capacitor includes a capacitor-element assembly, a package covering the capacitor-element assembly, and a supporter embedded in the package. The capacitor-element assembly includes a capacitor element having a first electrode, and a busbar joined to the electrode of the capacitor element. The busbar has a terminal. The package is made of norbornene-based resin and covers the capacitor-element assembly while exposing the terminal of the busbar. The supporter has first and second end section and is made of heat-conductive insulating material. The first end section contacts the capacitor-element assembly. The second end section is exposed from the package. This molded capacitor has high heat resistance and a small, light-weighted body, and can be manufactured inexpensively. | 05-05-2011 |
