摘要： An inductor and method for making the same are provided. The inductor includes a coil that is not wound around itself. The coil may have an “S”-shape. The coil has two leads extending from opposite ends of the coil. An inductor body surrounds the coil and portions of the leads. The leads may be wrapped around the body to create surface mount leads on the exterior of the inductor.

摘要： A coil component includes an insulating base body and a coil conductor arranged in the base body and having a winding portion extending around a coil axis. The insulating base body includes a magnetic body portion made of a magnetic material and a magnetic gap portion made of a low-permeability material having a lower relative permeability than the magnetic material. The magnetic gap portion is shaped like a ring when seen in a direction along the coil axis and arranged within the winding portion. The magnetic body portion includes a first region positioned within the winding portion, a second region positioned opposite the first region with respect to the magnetic gap portion in the direction along the coil axis, and a third region arranged within a through hole defined by an inner peripheral surface of the magnetic gap portion, where the third region connects together the first and second regions.

摘要： A motor-driven compressor includes a housing that accommodates an inverter device. A noise reduction unit of the inverter device includes a common mode choke coil including a looped core and two windings wound around the core, and a looped conductor surrounding the two windings. The conductor is configured so that an induced current flows in the conductor in a circumferential direction of the conductor to resist changes in a leakage magnetic flux from the core. The conductor includes a housing-side conductor portion located between the two windings and the housing. The housing-side conductor portion includes a through-hole that extends through the housing-side conductor portion in the axial direction of the core. The housing includes a projection that is inserted into the through-hole and opposed to the two windings.

摘要： Recesses are formed by chamfers grooved along ridges of a wire-wound core portion having a substantially quadrangular-prism shape. Each of the recesses has a sloping surface that is inclined at an obtuse angle with respect to inner end surfaces of flanges and that extends in a direction away from the inner end surfaces. The sloping surface improves mechanical strength of a core. Preferably, an end portion of the sloping surface closer to the corresponding inner end surface is aligned with the peripheral surface or located closer to a center axis of the wire-wound core portion than the peripheral surface in a direction from the peripheral surface toward the center axis.

摘要： The objective is to adjust the magnetic resistance at each coil mounting part to the desired level. The inductor includes a core and coils. The core includes the coil mounting parts extending in the Y direction and arranged in the X direction. The coils are externally fitted around each coil mounting part. The positions of the end faces on the Z− direction side of the coil mounting parts are aligned in the Z direction. The position of the end face on the Z+ direction side of at least a predetermined coil mounting part and the position of the end face on the Z+ direction side of another coil mounting part are different from each other in the Z direction. The cross-sectional area of the predetermined coil mounting part and the cross-sectional area of another coil mounting part are different from each other when viewed in the Y direction.
