  • Patent number: 11282649
    Abstract: A capacitor includes a capacitor element, a first electrode, a second electrode, a first bus bar, a second bus bar, an exterior member, and a filler resin. The first electrode is disposed on an end face of the capacitor element. The second electrode is disposed on another end face of the capacitor element. The first bus bar is connected to the first electrode. The second bus bar is connected to the second electrode. The exterior member covers the capacitor element. The filler resin fills an interior of the exterior member. The exterior member includes a metal laminate film and has an opening to lead out a part of the first bus bar and a part of the second bus bar. The opening is sealed with the filler resin.

  • Patent number: 10796850
    Abstract: A metalized film includes a dielectric film having a strip-shape, and a metal vapor-deposited electrode. An insulation margin is provided on a first end portion located at one end in a width direction of the dielectric film. A plurality of first slits each extending in a longitudinal direction of the dielectric film and a plurality of fuses are provided close to a second end portion located at an other end in the width direction. The metal vapor-deposited electrode includes a plurality of divided electrodes separated by a corresponding one of a plurality of second slits. Each of the plurality of second slits extends from the insulation margin to a corresponding one of the plurality of first slits. When the metalized film is cut along a cutting line extending in the width direction, at least two divided electrodes among the plurality of divided electrodes are respectively cut at the cutting line.

  • Patent number: 10692656
    Abstract: A film capacitor according to the present disclosure includes a first film and a second film wound in a stacked state and a first deposition electrode and a second deposition electrode that are formed by metal deposition. The second deposition electrode includes widthwise slit portions, the widthwise slit portions crossing the second deposition electrode in its widthwise direction, split electrodes split by the widthwise slit portions, and a longitudinal slit portion extending in a longitudinal direction of the second deposition electrode in an ineffective electrode region shifted from an effective electrode region in the widthwise direction of the second deposition electrode. Each split electrode includes a first fuse portion bridging over a longitudinal slit portion and a second fuse portion that bridges over a widthwise slit portion and can be fused with a current smaller than a current for the first fuse portion.

  • Publication number: 20180277304
    Abstract: A metalized film includes a dielectric film having a strip-shape, and a metal vapor-deposited electrode which is formed on a surface of the dielectric film. An insulation margin is provided on a first end portion which is located at one end in a width direction of the dielectric film. A plurality of first slits each extending in a longitudinal direction of the dielectric film and a fuse disposed between a corresponding pair of the plurality of first slits are provided close to a second end portion which is located at the other end in the width direction. The metal vapor-deposited electrode includes a plurality of divided electrodes which are separated by a corresponding one of a plurality of second slits, and are arranged in the longitudinal direction. Each of the plurality of second slits extends from the insulation margin to a corresponding one of the plurality of first slits.
