Abstract
A DC link capacitor (8) comprises a capacitor housing, a plurality of capacitor cells (1), each comprising a film capacitor element (2) with a wound metallized film and two contact terminals (3a, 3b) connected to the metallized plastic film. The plurality of capacitor cells (1) are arranged in the capacitor housing (4) and are sealed therein by means of a sealing material (7). The contact terminals (3a, 3b) are electrically isolated from each other and protrude separately out of the sealing material (7), in order to be connected by means of bus bars.
