Abstract: A coil component includes a first core, a second core, a lead wire, an outside mark, and an inside mark. The first core includes a winding portion and a pair of core ends. The second core connects a pair of the core ends and includes an inside surface and an outside surface. The lead wire is wound around the winding portion. The outside mark is formed on the outside surface of the second core and designed to change its arrangement at the time of rotating the second core by 90 degrees in a rotational direction whose central axis is along a normal direction of the outside surface. The inside mark with undulation is formed on the inside surface of the second core and designed to change its arrangement at the time of rotating the second core by 90 degrees in the rotational direction.

Abstract: Disclosed herein is a pulse transformer that includes a drum core having a winding core portion and first and second flange portions, a plate core connected to the first and second flange portions, and a plurality of wires that are wound around the winding core portion. The first and second flange portions and the plate core are ground such that an inductance of the pulse transformer is 350 μH or more when a bias current of 8 mA is applied to the wires.
