Abstract:
A metallized film capacitor includes: a metallized film columnar body including two metallized films that are laminated and wound, the two metalized films each including a vapor-deposited metal film with a plurality of vapor-deposition-free slits and fuse portions each interposed between the vapor-deposition-free slits, and a polyvinylidene fluoride dielectric film, the metallized film columnar body having two electrode extraction surfaces; metal-sprayed parts disposed respectively on the two electrode extraction surfaces; and outgoing terminals joined respectively to the metal-sprayed parts. Each of the two metallized films has a shape with successive sloped ridges and valleys in a cross-section orthogonal to a winding direction, and the two metallized films are laminated such that the ridges and valleys of one of the metallized films are aligned with the ridges and valleys of the other one of the metallized films.
