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 winding part, first and second terminal electrodes provided on the first flange part of the drum-shaped core, third and fourth terminal electrodes provided on the second flange part of the drum-shaped core, a first coil wound around the winding core part connected between the first and third terminal electrodes, and a second coil wound around the winding core part connected between the second and fourth terminal electrodes. The first and second coils cross each other at the first drawing part positioned between the winding part and the first flange part. The first coil is constituted by two or more wires.

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.
