1. A device comprising:
a winding carrier;
at least one winding of a wire arranged around the winding carrier;
a magnetic core;
at least one first electrical terminal; and
at least one second electrical terminal;
wherein the winding carrier encloses the magnetic core at least in regions such that an insulation path between the at least one first electrical terminal and the at least one second electrical terminal along a lower side of the device does not comprise a bridging by the magnetic core,
wherein the winding carrier is formed as a single piece and has a lead-through, the magnetic core being arranged in the lead-through, and
wherein the winding carrier further comprises a first opening at a side face for inserting a first core part and a second opening at an upper side for inserting a second core part, the lead-through being accessible from outside of the device only through the first opening and the second opening.
