  • Publication number: 20250069803
    Abstract: A coil component manufacturing apparatus for winding a twisted portion of wires at a desired position of a core. A coil component manufacturing apparatus including a nozzle through which a plurality of wires can be inserted, a wire twisting mechanism that holds a core, rotates the core relative to the nozzle in a direction of twisting the wires, and forms a twisted portion in which the wires are twisted between the nozzle and the core, a wire winding mechanism that holds the core, rotates the core relative to the nozzle in a direction of winding the twisted portion is wound around the core, and winds the twisted portion around the core, and a guide member positioned closer to the core than the nozzle. The guide member guides the twisted portion to a predetermined position of the core when the twisted portion is wound around the core.

  • Publication number: 20250054683
    Abstract: A coil component includes a drum core including a core portion and first and second flange portions; first, second, third and fourth outer electrodes; and first and second wires. The second wire includes first and second winding portions. The first winding portion is a portion including plural turns wound around an outer periphery of the first wire. The second winding portion is on a second wire end side relative to the first winding portion and includes less than 1.0 turn continuously wound around the outer periphery of the first wire. The first winding portion includes a first traverse portion, which runs across the first wire without running in the same layer as the first wire in one turn immediately preceding an end portion of the first winding portion where the end portion is the closest to the second wire end in the first winding portion.

  • Publication number: 20250054682
    Abstract: A coil component includes a drum core including a core portion, first and second flange portions; first, second, third and fourth outer electrodes; and first and second wires. When the first wire is traced from a first wire end to a second wire end, a turn including a last point that makes contact with an outer surface of the core portion is referred to as an N-th turn. When the second wire is traced from a first wire end to a second wire end, a turn including a last point that makes contact with the outer surface of the core portion is referred to as an M-th turn. The M-th turn of the second wire and the N-th turn of the first wire do not include an intersection portion at which the M-th turn of the second wire and the N-th turn of the first wire intersect.

  • Publication number: 20240371560
    Abstract: A coil component includes a drum-shaped core including a core part having a circumferential surface including a first side surface and a second side surface parallel to each other; and a coil including two wires wound around the core part in the same direction. The coil has a first twisted wire part having the two wires twisted together on the first side surface, and a second twisted wire part having the two wires twisted together on the second side surface. The first twisted wire part and the second twisted wire part are identical in shape.
