    摘要： A choke comprising a magnetic core (2) having a centre line that forms a closed loop, the choke has a choke axis (4) around which the magnetic core (2) is located, and a coil (6) wound around the magnetic core (2), the coil (6) has a plurality of turns (601 - 608), each of the turns (601 - 608) has a width perpendicular to lengthwise direction of the turn, and a thickness perpendicular to both lengthwise direction of the turn and the width. The coil (6) has a cross-section whose shape varies along lengthwise direction of the coil (6), such that each turn (601 - 608) has an inner portion (651) and an outer portion (652) whose width is substantially greater than width of the inner portion (651), the outer portion (652) is located further from the choke axis (4) than the inner portion (651).

    摘要： A magnetic component includes a magnetic core and a first winding module. The magnetic core has two opposite openings and at least one magnetic column. The first winding module has a plurality of annular metal plates disposed around the at least one magnetic column. Each of the annular metal plates has an electrical connection end, an annular portion and a heat-dissipating end. The electrical connection end and the heat-dissipation end are located at the two opposite openings of the magnetic core respectively. A thermal-dissipating area of the heat-dissipating end is greater than a cross-sectional area of a connection portion between the heat-dissipating end and the annular portion.

    摘要： A noise filter including a conductor and an annular core. The conductor has a wound portion. The annular core is formed of a magnetic material and passes through the wound portion. The annular core is formed of a pair of split cores that are assembled together with joining surfaces on both ends to be joined to each other. At least one of a recess portion and a projection portion that engage with each other is formed on the joining surfaces of the split cores which are joined to each other.

    摘要： Two wire materials for coils can be efficiently processed into the same winding state and a configuration in which various characteristics and a cost thereof fall within a predetermined range is formed.
    Provided is a transformer device to be mounted in a LAN for networking, in which a wire material 11A for a primary coil and a wire material 11B for a secondary coil are wound around an annular core 31 to allow a signal component to pass from the wire material 11A for the primary coil to the wire material 11B for the secondary coil, wherein the wire material 11A for the primary coil is formed of a one-layer insulating wire material, and the wire material 11B for the secondary coil is formed of a three-layer insulating wire material, respectively, and the wire materials are wound around the core 31 in the form of a twisted wire (11) formed by intertwisting two insulating wire materials 11A and 11B.

    摘要： A multi-layer, multi-turn structure for an inductor having a plurality of conductor layers separated by layers of insulator is described. The inductor further comprises a connector electrically connected between the conductor layers. The structure of the inductor may comprise a cavity therewithin. The structure of the inductor constructed such that electrical resistance is reduced therewithin, thus increasing the efficiency of the inductor. The inductor is particularly useful at operating within the radio frequency range and greater.
