Abstract
The capacitors are offset-wound and the dielectric strips are metallized on one side while the metallic contacts are mounted on both front sides. The dielectric strips are metallized over their whole width and individual dielectric strips are etched on their front sides. The capacitor consists of two plastics strips (1, 2) which are laterally displaced relative to each other and wound into one another. A contact (3) is positioned on the projecting edges. When insulating edges are dispensed with in comparison with conventional capacitors, a considerably more favourable ratio of the effective band width (be) to the actual winding width (bw) is the result.
