Abstract

The invention relates to an inductive component, which has a ring core of soft magnetic material which annularly surrounds an inner opening and which has at least two electrically conductive conductor pieces, which extend less than completely around the ring core through the inner opening and which each have two conductor end sections. The conductor end sections are led away from the ring core parallel to each other and perpendicularly to the ring core and are electrically connected to each other so as to form at least one winding. The conductor end sections are arranged outside of the inner opening and outside of an imaginary extension of the inner opening in the axial direction. The invention further relates to a production method for such an inductive component and to a current-compensated choke.
