Abstract
This extended-foil capacitor comprises a plurality of flattened foil rolls stacked side-by-side. Each foil roll comprises two sheets of foil rolled up in nesting, face-to-face relationship and dielectric film positioned between said foil sheets and electrically insulating the foil sheets from each other. At one end of each foil roll, one of the foil sheets entends beyond both the dielectric film and the other foil sheet in the roll to provide first foil extensions at said one end of the roll. Adjacent foil rolls in the stack have their first foil extensions positioned adjacent each other at one end of the adjacent rolls. At said one end of the adjacent rolls, there is a joint formed by ultrasonic welding and joining together the first foil extensions. This joint includes within it dozens of superposed foil extensions arranged in a substack and joined together by solid-state metallurgical bonds between juxtaposed foil extensions.
