Claim Text:
1. A current-compensated choke with two current paths, wherein each current path comprises a plurality of windings that are connected in parallel and wound on a common core, wherein each winding forms an individual layer around the core such that each individual layer includes only one winding, wherein the individual layers lie one on top of another and are at least partially laterally offset from one another, and wherein the windings belonging to the two current paths are alternately arranged one on top of another; and wherein the windings are arranged in such a way that magnetic fields generated by the current paths at least for the most part compensate one another, wherein all windings have the same winding direction, which allows cancellation of magnetic fields caused by current paths having opposite directions; wherein the current-compensated choke further comprises a cap, wherein the windings are substantially surrounded by the cap and wherein the cap serves as part of the core.
