A shielded inductor and a method of making a shielded inductor are provided. The shielded inductor includes a core body surrounding a conductive coil, leads in electrical communication with the coil, and a shield covering at least parts of the outer surface of the core body. An insulating material may be provided between parts of the core body and parts of the shield. A method of making a shielded inductor is also provided.

Method of making a shielded inductor

Shielded inductor and method of manufacturing

An inductor includes an inductor body having a top surface and a first and second opposite end surfaces. There is a void through the inductor body between the first and second opposite end surfaces. A thermally stable resistive element positioned through the void and turned toward the top surface to forms surface mount terminals which can be used for Kelvin type sensing. Where the inductor body is formed of a ferrite, the inductor body includes a slot. The resistive element may be formed of a punched resistive strip and provide for a partial turn or multiple turns. The inductor may be formed of a distributed gap magnetic material formed around the resistive element. A method for manufacturing the inductor includes positioning an inductor body around a thermally stable resistive element such that terminals of the thermally stable resistive element extend from the inductor body.

Inductor with thermally stable resistance

A high current, low profile inductor includes a conductor coil surrounded by magnetic material to form an inductor body. An inductor body is formed around the inductor coil and includes a resin and a magnetic material compressed while it is dry and surrounding the inside and the outside of the coil.

Method for making a high current low profile inductor

A method for making a high current low profile inductor includes forming an inductor element comprising a coil having an open center and an outside surface, the coil also having first and second coil ends, making a dry mixture comprising a dry resin and an insulated dry powdered magnetic powder, and compressing the dry mixture around the outside surface of the coil and within the open center of the coil to create an inductor body without liquefying the dry mixture, whereby the inductor body engages the coil both within the coil open center and also the coil outside surface.

A high current, low profile inductor includes a conductor coil surrounded by magnetic material to form an inductor body. The inductor coil is formed from a flat plate which is cut into a sine-shaped configuration and then is folded in accordion fashion to create a helical coil.

Inductor coil

Inductor coil and method for making same

A high current, low profile inductor (IHLP) includes a conductive coil molded within an inductor body substantially free from ferrite materials and comprising powdered iron materials. The method comprises pressure molding the inductor body substantially free from ferrite materials and comprising a powdered magnetic material within the hollow core of the coil and completely around the coil so that the magnetic material is substantially free from voids therein without shorting out the coil.

A method for making a high current, low profile inductor includes a wire coil having an inter coil end and an outer coil end. A magnetic material completely surrounds the wire coil to form an inductor body. First and second leads connected to the inner coil end and the outer coil end respectively extend through the magnetic material to the exterior of the inductor body. The method of operation involves pressure molding the magnetic material around the wire coil.

Method for making a high current, low profile inductor

method for making a high current, low profile inductor includes taking an elongated plate, cutting a plurality of slots in the sides of the plate so as to form a plurality of cross segments extending transversely with respect to the length of the plate and a plurality of connecting segments extending approximately axially with respect to the longitudinal axis of the plate. The method further requires bending the segments transversely with respect to the plate axis so as to place the opposite flat surfaces of the cross segments in planes parallel to one another and facing in an axial direction with respect to the longitudinal plate axis.

Method for making inductor coil structure

A high current, low profile inductor includes a wire coil having an inter coil end and an outer coil end. A magnetic material completely surrounds the wire coil to form an inductor body. First and second leads connected to the inner coil end and the outer coil end respectively extend through the magnetic material to the exterior of the inductor body. The method of operation involves pressure molding the magnetic material around the wire coil.
