    Abstract: In a magnet, an insulating layer is fixed to an upper surface of the magnet provided with the insulating layer, but is not fixed to a lower surface of the magnet above the insulating layer. Therefore, even when the magnet expands or contracts due to a temperature change, stress is less likely to occur at an interface between the insulating layer provided on the upper surface of the magnet and the magnet above the insulating layer.

    Abstract: A pulse transformer includes a drum core having a winding core, a first flange provided at one end of the winding core in a first direction, and a second flange provided at the other end of the winding core in the first direction. First, second, third, and fourth terminal electrodes are provided in the first flange, and fifth, sixth, seventh, and eighth terminal electrodes are provided in the second flange. First, second, third, and fourth wires each have one end connected to a different one of the first to fourth terminal electrodes and the other end connected to a different one of the fifth to eighth terminal electrodes. A length of the drum core in the first direction and the second direction, perpendicular to the first direction, are substantially equal to one another, such that a planar shape of a mounting region of the pulse transformer is substantially square.

    Abstract: Disclosed herein is a coil component that includes a drum-shaped core having a first flange part provided at one end of a winding core part, first to fourth terminal metal fittings formed on the first flange part so as to be arranged in this order in a second direction, and first to fourth wires wound around the winding core part. One ends of the first to fourth wires are connected to different ones of the first to fourth terminal metal fittings. A distance between the first and second terminal metal fittings is larger than the distance between the third and fourth terminal metal fittings. An amount of an adhesive used to bond each of the third and fourth terminal metal fittings is greater than an amount of an adhesive used to bond each of the first and second metal fittings.
