Abstract: A magnetic component, with a first and a second U/UR core (U1, U2) assembled to a first O-shaped core assembly, wherein an U/UR core has—according to its shape—a first post and a second post with free ends on one side and a leg connecting the first post and the second post on their other side, wherein the first and the second U/UR core (U1, U2) are assembled with their free ends abutting each other to form the first O-shaped core assembly. The free ends of a third U/UR core (U3) are abutting the outside of the first O-shaped core assembly on one side and that the free ends of a fourth U/UR core (U4) are abutting the outside of the first O-shaped core assembly on an opposite side. In another embodiment, the leg of a third U/UR core (U3) is abutting the outside of the first O-shaped core assembly, wherein the ends of a fourth U/UR core (U4) are abutting the ends of the third U/UR core (U3). In a further embodiment, the ends of a third U/UR core (U3) are abutting the outside of the first O-shaped core assembly.
