Abstract (en)
[origin: WO2019179749A1] The invention relates to an inductive component having a planar conductive track structure. The planar conductive track structure is surrounded along a predetermined section by a ferromagnetic core. For targeted control of the current flow inside the planar conductive track structure and, in particular, of the current density in the cross-section of the planar conductive track structure, gaps are provided in a targeted manner in the ferromagnetic core. The gaps in the ferromagnetic core are arranged in regions above and/or below the planar conductive track structure.
