A metalized film capacitor includes a metal deposition electrode on a dielectric film. The metal deposition electrode includes slits provided and divided only at a side opposite to low resistance portions connected to a metalized contact, and fuses provided between the slits. In a laminated metalized film, slits provided at a central portion in a width direction of the metalized deposition electrode and extending in the longitudinal direction of the dielectric film do not overlap with each other.

Film capacitor and method of manufacturing the same

A method of manufacturing a both-side metallized insulation film comprises steps of: depositing zinc or a blend of zinc and aluminum onto both sides of an insulation film; and winding this metallized film into a product roll. The method is characterized in spraying an oxidizing gas onto a deposited layer on an inner side of the insulation film to be wound, during the winding step. During a vacuum deposition step, an oil layer is formed on at least one side of the metallized film. In addition, an oxide layer is formed by exposing a deposited layer on at least one side to oxygen, or by spraying an oxygen-containing gas onto the deposited layer on at least one side during the winding of the metallized film into the product roll.

The metallized film capacitor comprises: a plurality of capacitor elements () provided with metallized contact electrodes () on both ends in the width direction; a bus-bar () to connect each of a plurality of electrodes () on one end; and a capacitor case () to house a plurality of capacitor elements (), wherein a plurality of capacitor elements () are arranged in the capacitor case such that one side of electrodes () faces the opening surface of capacitor case () and each electrode () of one of both ends of each capacitor element () are positioned generally coplanarly.

Metallized film capacitor

A metallized-film capacitor includes a slit () at approx. center of the width (W) of an effective electrode which actually forms a capacitance of a pair of deposited electrodes (). Divisional electrodes () exist at a place between the center and insulation margins (), and the electrodes () are coupled in parallel to each other by fuses () disposed away from metallized contacts (). Such a structure as placing fuses () away from the contacts () allows reducing a current supplied from the contacts () and running through fuses (), thereby lowering heat generated from fuses (). As a result, a temperature rise in the metallized-film capacitor can be suppressed.

A metallized film capacitor is made by winding or laminating a both-side metallized polypropylene (PP) film and a non-metallized PP film. Limiting the heat shrinkage factor and the thickness of the PP films, the position of deposited electrodes, and the rate of the peeled area of the deposited electrodes to a certain range provides a metallized film capacitor having improved dieletric strength, tan &#x3b4;, and charge-discharge characteristics.
