摘要： In a magnet stack, an eddy current channel is cut off by an insulating layer in an insulating region of facing surface regions of the pair of magnets. Meanwhile, in a conducting region of the facing surface region of the pair of magnets, electrons can move between the pair of magnets via a conductor, and heat can be exchanged between the pair of magnets by the movement of electrons. Therefore, in the magnet stack, by cutting off the eddy current channel in the insulating region of the facing surface region of the pair of magnets, the degradation in magnet performance is suppressed and the cooling efficiency of the magnet is enhanced in the conducting region.

摘要： 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.

摘要： A pulse transformer includes a winding drum and a coil portion in which wires are wound around the winding core. The coil portion includes a first general winding area, a second general winding area, and a low density winding area. In the first general winding area, the wires are mutually closely wound around the winding core. In the second general winding area, the wires continuing from the wires of the first general winding area are mutually closely wound around the winding core. The low density winding area is formed along a winding axis of the winding core between the first general winding area and the second general winding area and has a low winding density of the wires along the winding axis.

摘要： Disclosed herein is a coil component that includes a drum-shaped core having a flange portion and a winding core around which a wire is wound. The flange portion includes first and second side surface opposite to each other, and a mounting surface. The mounting surface of the flange portion includes first and second convex portions and a concave portion positioned therebetween. The first convex portion has a third side surface parallel to the first side surface of the flange portion. The second convex portion has a fourth side surface parallel to the second side surface of the flange portion. A level difference between the first side surface and the third side surface is larger than a level difference between the second side surface and the fourth side surface.

摘要： Disclosed herein is a coil component that includes first and second terminal electrodes provided on the core. The first wire includes a first lead section extending from a winding core portion toward the first terminal electrode so as to cross the winding core portion, and a first connecting section connected to the first terminal electrode. The second wire includes a second lead section extending from the winding core portion toward the second terminal electrode so as to cross the winding core portion, and a second connecting section connected to the second terminal electrode. The first lead section crosses the second lead section so as to pass under the second lead section. The second connecting section is located closer to a far side in an extending direction of the winding core portion than the first connecting section.
