Abstract: A winding support includes a tube for receiving one of the legs of a ferromagnetic core of a magnetic component such that half-legs of the leg face each other in the tube. The magnetic component further includes windings which correspond to the leg and which are wound on the tube. The winding support includes a wedging protrusion and at least one spacing wall. The wedging protrusion is formed on an inner surface of the tube so as to define an air gap between the opposing half-legs. The at least one spacing wall, which is formed opposite the wedging protrusion and on an outer surface of the tube, is configured to keep at least one of the windings away from the air gap.
