Abstract: An electronic component comprises: a magnetic core having a flat base and a core, the flat base having a top, a bottom, and first and second opposite sides, the core is on the top; a winding having an edgewise coil including a wound flat wire and the core, the winding having two non-wound flat wires extending therefrom; and a magnetic exterior body covering the core and the edgewise coil. The two non-wound flat wires extend along the top, the first side, the bottom and then the second side, and the two non-wound flat wires are non-adhesively positioned around the flat base. The two non-wound flat wires on the bottom are externally exposed electrodes. The second side inclines towards the core. The two ends of the two non-wound flat wires are embedded into the magnetic exterior body to fix the two non-wound flat wires to the magnetic exterior body.

Abstract: A method for manufacturing an electronic component is provided. The method includes placing a T-shaped core and an air-core coil in a mold, placing a mixture of a metal magnetic material and a thermosetting resin into the mold so as to embed the T-shaped core and the air-core coil in the mixture, applying pressure in a range of 0.1 to 20.0 kg/cm2 to the placed mixture so that a shape of the placed mixture conforms to the T-shaped core, the air-core coil, and the mold, and, after applying the pressure, heating the mixture at a predetermined temperature for a predetermined time so that the placed mixture is hardened.

Abstract: An electronic component includes a magnetic core member, a winding and a magnetic exterior body. The magnetic core member has a flat base and a core. The flat base has a top surface, a bottom surface, a first side surface and a second side surface opposite to the first side surface. The core is located on the top surface of the flat base. A winding has an edgewise coil and two non-wound flat wires that extend from the edgewise coil. A magnetic exterior body covers at least the core and the edgewise coil. The two non-wound flat wires continuously extend along the top surface, the first side surface, the bottom surface and the second side surface of the flat base in this order. The two non-wound flat wires located on the bottom surface work as electrodes.

Abstract: An inductor includes an air-core coil assembled with a T-shaped core and a composite magnetic material and resin mixture embedding the T-shaped core and the air-core coil. The air-core coil has: a coil member having a coil axis and first and second sides opposite to each other; and first and second leads that are integrally connected to the coil member. The first and second leads respectively have: first and second bent members at the first side; first and second ends at the second side; and first and second bottom extensions respectively connected between the first and second bent members and the first and second ends. The first and second bent members extend in a first direction parallel to the coil axis, the first and second ends extend in a second direction parallel to the coil axis, and the first and second bottom extensions extend perpendicular to the coil axis.

Abstract: A method for manufacturing an electronic component for avoiding electromagnetic interference includes: (a) placing a T-shaped core and an air-core coil in a metal mold; (b) injecting a mixture of a composite magnetic material and a resin into the metal mold so that the T-shaped core and the air-core coil are embedded by the mixture; (c) heating the mixture at a first temperature; (d) adjusting an outer shape while removing excessive mixture; and (e) hardening the mixture. The method may further include a process of polishing an outside of the hardened mixture. The method may further include a process of applying a pressure of 0.1 to 20.0 kg/cm2 to the mixture for adjusting an outer shape of the mixture by a movable punch of a press machine before the hardening process.
