10. An inductive component (1), having:
a planar printed conductor structure (10) which comprises an upper side (11), and an underside (12), wherein the upper side (11) is arranged opposite the underside (12), and
a ferromagnetic core (20), which is arranged around the planar printed conductor structure (10),
wherein the ferromagnetic core (20) incorporates a first plurality of gaps (21) in a region of the upper side (11) of the planar printed conductor structure (10) and a second plurality of gaps (21) in a region of the underside (12) of the planar printed conductor structure (10), and wherein each of the first plurality of gaps (21) or each of the second plurality of gaps (21) is filled with a different dielectric fill material.
