An electric double-layer capacitor comprises a gasket encircling a pair of polarizable electrodes provided on opposite sides of a separator, and a pair of collectors provided on outer sides of the polarizable electrodes and sealed to the gasket. The gasket is formed of a base of vulcanized rubber and resin layers obtained by fusion-welding polyolefin resin on both surfaces of the base, and the collectors are heat-sealed to the gasket.

Electrolytic double-layer capacitor

A tubular ceramic capacitor in which a lead terminal for leading out an internal electrode is formed of a Dumet wire, the internal electrode and an external electrode are plated to be formed at the inner and outer surfaces of a tubular ceramic dielectric except for both end faces thereof respectively, the lead terminal of the Dumet wire having a diameter substantially equal to a diameter of an inner bore of the dielectric where the internal electrode is formed and being inserted into the bore substantially throughout the whole length thereof so as to be fixedly soldered, and a metallic cap terminal having an inner diameter substantially equal to an outer diameter of the dielectric and a lead wire projecting from the outer surface of the closed end of the cap terminal, is fitted onto the dielectric in relation of contacting with the external electrode, thereby reducing an amount of solder used for mounting the lead terminal, thus making it possible to prevent the internal electrode from peeling off.

Tubular ceramic capacitor

A capacitor arrangement for use in filtering high frequency noises includes a dielectric disc plate and electrodes deposited on opposite flat surfaces of the disc plate. A terminal leg extends from one electrode for the connection with ground, and two terminal legs extend from the other electrode for the connection with consecutive lead lines. The terminal legs connected with the consecutive lead lines are mounted with magnetic elements for increasing the inductance in the terminal legs.
