1. An inductive component comprising:
at least one electrical conductor;
a coil former with a hollow-shaped winding former, on a surface of which the at least one electrical conductor is wound around the winding former;
a magnetic core arranged in a first cavity of the winding former;
a potting material,
wherein the at least one electrical conductor is surrounded by the potting material,
wherein the potting material has no directly adherent contact with the magnetic core,
wherein the magnetic core comprises a first part-body and a second part-body, which are connected to one another,
wherein at least one of the first part-body or the second part-body of the magnetic core comprises a leg arranged in the first cavity of the winding former and at least one further leg arranged outside the first cavity of the winding former, and
wherein the first part-body of the magnetic core is arranged as an U core with the leg, which is arranged in the first cavity of the winding former, and the second part-body of the magnetic core is formed as an I core; and
a protective body with a covering element configured to protect the at least one electrical conductor, wherein the coil former is fastened to the protective body and the at least one electrical conductor is covered by the covering element,
wherein the coil former and the protective body are arranged such that the winding former is fastened in a self-sealing manner to the protective body so that any leaking of the potting material from a second cavity between the at least one electrical conductor and the covering element of the protective body is prevented,
wherein the covering element comprises a bottom part, which lies opposite the at least one electrical conductor, and respectively on both sides of the bottom part a side part,
wherein the winding former has flanges for delimiting a winding region,
wherein either the flanges have in each case a recess and the side parts have in each case a web or the flanges have in each case the web and the side parts have in each case the recess,
wherein the recess is a channel, and
wherein the coil former is fastened to the protective body, in that each of the webs engages in one of the recesses.
