A common mode choke coil includes a core, and first and second coils opposed to each other and wound on the core. The core can have a square shape, or an elongated shape having a long axis and a short axis when viewed in a direction along a central axis of the core. Each of the first and second coils is a single-layer coil. An area of a cross-section of the core taken perpendicular to a circumferential direction of the core is constant in the circumferential direction of the core. The cross-section of the core has a quadrilateral shape.

A coil component includes a wire; a core having a winding core around which the wire is wound and a flange portion provided at an end portion of the winding core in an axial direction; and a terminal electrode to which the wire is connected and that is provided on the flange portion. The terminal electrode has a projecting portion that sticks out in the axial direction relative to the flange portion. The projecting portion has a flat surface along which the wire is thermocompression-bonded. Thermocompression bonding of the wire is performed in a state where an interval between a head surface of a heater chip and the flat surface becomes narrower from a flange portion side toward a front end side of the projecting portion. A degree of crushing of the wire decreases from the front end side toward the flange portion side of the projecting portion.

The present disclosure is related to a wireless charging module and an electronic device thereof. The wireless charging module includes a base, at least one magnetic shielding sheet, and a coil. The base includes at least two metal melting regions. Each metal melting region includes an opening, and a blocking region disposed at the opening. The magnetic shielding sheet is disposed on the base. The magnetic shielding sheet partially exposes the two metal melting regions and the openings. The coil is disposed on the magnetic shielding sheet. The coil includes two leads. The two leads are respectively disposed on the two metal melting regions. The two leads are disposed in the blocking regions and the openings. The electronic device includes the wireless charging module and a power supply. The wireless charging module is electrically connected to the power supply.

A coil component includes: a body including a molded portion having one surface and the other surface opposing each other, and a cover portion disposed on the one surface of the molded portion; a wound coil disposed between the molded portion and the cover portion in the body, and having first and second lead-out portions extending to one surface of the body; a first recess portion disposed in the one surface of the body; a first external electrode disposed on the one surface of the body to be connected to the first lead-out portion, and disposed along a surface of the first recess portion to have a first groove disposed therein; and a second external electrode disposed on the one surface of the body and connected to the second lead-out portion.

A common mode choke is provided, including a hollow ferrite core, a plurality of coils wound around the ferrite core, and a substrate. Each of the coils has a first end and a second end. The substrate is disposed on the side of the ferrite core and has a plurality of through holes. The first and second ends of the coils are engaged in the through holes. When viewed along the central axis of the ferrite core, the first and second ends of the coils are located on the outer side the ferrite core.

A inductive component is provided, which comprises a magnetic core, an insulation body formed of an electrically insulating material and having the magnetic core accommodated therein, and a coil body having at least one winding wound thereon. The insulation body comprises at least two mechanically connected insulation wall sections, which each face, at least partially, a respective side surface section of the magnetic core. The coil body comprises at least one contact element attached to a side surface section of the coil body and used for establishing an electric connection to the at least one winding, and a magnetic core accommodation in which the magnetic core accommodated in the insulation body is partially accommodated. A side surface section of the magnetic core, which faces the contact element, is covered, at least partially, by an insulation wall section of the insulation body.

An inductor component includes a core including a substantially column-shaped shaft and a pair of supports provided at both ends of the shaft; terminal electrodes provided on the supports; a wire wound around the shaft and including end portions connected to the terminal electrodes; and a bottom cover member that covers a boundary portion between the shaft and one of the supports at a bottom of the shaft. The wire is exposed at a side of the shaft.

Terminal electrodes are disposed on mounting surfaces of flanges of a substantially drum-shaped core that are directed to a mounting substrate. A rounded surface is formed on the mounting surface. An end portion of the wire extends along the rounded surface from a side on which the inner end surface is present toward a side on which the outer end surface is present.

An inductor device includes first, second, third and fourth wire, first and second connector, and eight-shaped inductor structure. First and second wires are disposed in first and second areas. Third wire is disposed in first area and partially overlapped with first wire in a vertical direction, and third wire is coupled to second wire. Fourth wire is disposed in second area and partially overlapped with second wire in the vertical direction, and fourth wire is coupled to first wire. First connector is partially overlapped with first wire or third wire in the vertical direction, and is coupled to inner wire and outer wire of third wire. Second connector is partially overlapped with second wire or fourth wire in the vertical direction, and is coupled to inner and outer wire of fourth wire. Eight-shaped inductor structure is disposed on outer side of third wire and fourth wire.
