1. An inductive component comprising:
a core that has a core cross section, is ring-shaped and is made of soft magnetic material, and
a coil surrounding the core that is composed of two electrically conductive sections, wherein each of the sections comprises a basic U shape with two limbs, of which the first limb is longer than the second limb and the first limb is curved and, towards its end, projects away from a plane defined by the basic U shape;
the sections are fitted next to each other on the core such that the basic U shape of each section surrounds the core cross section on three sides, and
the first limb of a section is mechanically and electrically connected to the second limb of another section,
wherein the first limb of one of the sections and the second limb of one of the sections are insertable into each other at their ends,
wherein the first limb of the one section is flattened at its end to form an upper flattened surface and a lower flattened surface parallel to the upper flattened surface, the first limb comprises an opening of a specific form extending through the flattened surfaces, and the second limb of the other section comprises a form at its end that is complementary to the specific form of the opening, so that the second limb of the other section is inserted in the opening of the first limb of the one other section.
