ABSTRACT:
A coil capacitor with a capacitor coil placed in a cup-like housing. Capacitor foils are spirally wound up on a metal core which is a unitary one piece structure extending from a metal closure lid. The inner of the foils is electrically connected to the closure lid while the outer foil is electrically connected to a metallic cup-like housing, thus avoiding the necessity of electrical lead throughs. The edge of the closure lid is surrounded by a resilient seal which rests upon a support corrugation rolled into the housing wall and is captured by the rolled-in upper edge of the housing. A contact corrugation formed in the housing wall effectuates electrical connection with the outer foil.
