Abstract:
An inductive element comprises at least two core-parts including a magnetically permeable material and at least one winding of an electrical conductor which can be a foil winding, a stranded wire (litz) winding or a conventional wire winding. Each core-part has an elongated center piece with an outer winding surface. At each of its longitudinal ends, the center piece has a contact element with a lateral contact surface. The winding is wound directly on the core-parts without a bobbin or the-like. The core-parts of the inductive element are arranged with their longitudinal axes essentially in parallel in a manner that the lateral contact surfaces of each contact element abut on a lateral contact surface of another core-part. Such an inductive element can be manufactured by co-axially arranging the core-parts and using them as a roll-shaft. After the windings have been applied to the core-parts, they can be rearranged, i.e. “flipped over,” in a stack-like arrangement in order to form an inductive element.
