Abstract
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.
Claims17
A method of forming an electro-magnetic device for mounting on a circuit board, the method comprising:
- forming a coil;
- pressure molding a magnetic core body around the coil, the magnetic core body having a top surface and a bottom surface opposite the top surface, wherein the magnetic core body is formed so as to completely surround at least a portion of the coil;
- providing a first lead and a second lead connected to the coil, wherein a portion of the first lead and a portion of the second lead each extend along the magnetic core body;
- positioning a shield comprising a conductive material on the magnetic core body, wherein the shield covers at least a portion of the top surface of the magnetic core body including a central area of the top surface of the magnetic core body;
- and
- providing an insulating material or an adhesive between a surface of the shield facing the magnetic core body and the magnetic core body when the shield is positioned on the magnetic core body.
