An inductor component having such a characteristic property that the assembly of the inductor component can be made simple and the welded state in the inductor component can be made stable. The inductor component comprises a ring-shaped core; a coil which comprises a plurality of pin members, and in which adjacent pin members are connected and are wound around the coil; and a connecting member which connects the pin members adjacent to each other in a direction of an axis of the coil.

Inductor component and method for manufacturing same

Common mode choke coil

An inductor component and a method for manufacturing an inductor component that enables the inductor component to be miniaturized. An inductor component includes an annular core; and a coil including a plurality of pin members and wound on the core with neighboring pin members connected to each other. A first pin member and a second pin member both adjacent to each other have a welded part in which an end face of an end part of the first pin member and a peripheral surface of an end part of the second pin member are welded to each other. A width of a part, of the first pin member, except the welded part is smaller, as viewed from a direction along a center line of the end part of the second pin member, than a width of a part, of the second pin member, except the welded part.

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.

An inductor component includes a core having an annular shape; an insulating member that covers a portion of the core; a coil wound around the core and the insulating member; and a buffer member that is elastic. The core has a first face, a second face that crosses the first face, and a third face that faces the second face and crosses the first face. The insulating member is provided to cover the first face, a portion of the second face, and a portion of the third face. The core and the insulating member are bonded to each other with the buffer member interposed therebetween.

Inductor component

A method of manufacturing an electronic component capable of preventing entrance of a plating solution and a flux component at an interface to which an inner electrode of a ceramic element body is extended, and capable of forming an outer electrode of an arbitrary shape. A ceramic element body is made of a ceramic material containing a metal oxide, and part of an inner electrode is extended to extended surfaces of the ceramic element body. A base electrode is formed on each of the extended surfaces using a conductive paste to be connected to the inner electrode. Part of another surface of the ceramic element body adjacent to the extended surfaces is locally heated, and part of the metal oxide is reduced to form a reformed portion. A plating electrode is continuously formed over the base electrode and the reformed portion through a plating method to form outer electrodes.

Method of manufacturing electronic component and electronic component

An inductor component and a method for manufacturing an inductor component that enables miniaturization of the inductor component. An inductor component includes an annular core; and a coil including a plurality of pin members and wound on the core with neighboring pin members connected to each other. A first pin member and a second pin member both adjacent to each other have a welded part in which an end face of an end part of the first pin member and a peripheral surface of an end part of the second pin member are welded to each other. The welded part is not provided on an outer side edge of the second pin member as viewed from a direction orthogonal to a first plane containing a center line of the end part of the first pin member and a center line of the end part of the second pin member.

An inductor component includes an element body including a magnetic layer containing a resin and a magnetic powder; a coil wiring line arranged inside the element body; and an insulating coating film covering the coil wiring line and not including a magnetic material. In a cross section perpendicular to an extension direction of the coil wiring line, a top surface thickness of a part of the insulating coating film covering the top surface of the coil wiring line and a side surface thickness of parts of the insulating coating film covering side surfaces of the coil wiring line are less than or equal to 10 μm, and a corner thickness of parts of the insulating coating film that cover corners of the coil wiring line interposed between the top surface and the side surfaces is at least half of the top surface thickness and/or the side surface thickness.

An inductor component includes a bottom plate portion that includes a first main surface and a second main surface; an annular core that is disposed on the bottom plate portion; a coil that is wound around the core; and an electrode terminal that is attached to the bottom plate portion and electrically connected to the coil. The electrode terminal includes a mounting surface portion configured to connect to a mount substrate. The core is disposed on the first main surface of the bottom plate portion so that an axis of the core intersects the first main surface of the bottom plate portion. The mounting surface portion is exposed on the second main surface side of the bottom plate portion, and at least a part of the mounting surface portion overlaps the core when seen in a direction perpendicular to the first main surface of the bottom plate portion.

An inductor component includes a base body, a first coil line and a second coil line, a first substantially columnar line and a second substantially columnar line, and a third substantially columnar line and a fourth substantially columnar line. The first substantially columnar line is located closer to the third substantially columnar line than the fourth substantially columnar line. A minimum distance X1 between the first substantially columnar line and the third substantially columnar line is shorter than a minimum distance Y between a first portion of the first coil line and a second portion of the second coil line.

An inductor component comprising an insulating layer containing no magnetic substance, a spiral wiring formed on a first principal surface of the insulating layer and wound on the first principal surface, and a magnetic layer in contact with at least a portion of the spiral wiring.

Inductor component and method of manufacturing same

A coil component includes: a core having an annular shape; a coil wound around the core; and an electrode terminal for mounting the coil component. The electrode terminal is connected to the coil and has a mounting surface. The coil is formed by connecting a plurality of wire members. The electrode terminal has a recessed portion indented toward a back surface on a side opposite to the mounting surface. The wire member of the coil is connected to a back surface of a bottom portion of the recessed portion.
