Abstract: A method of manufacturing an inductive device includes: providing a magnetic base including a core column and defining a positioning trench that surrounds the core column; forming a coil structure including a coil body, a first extending section, and a second extending section, in which the coil body has a through hole, the first extending section includes a first bent portion and a first terminal portion connected thereto, and the second extending section includes a second bent portion and a second terminal portion connected thereto; arranging the coil structure in the positioning trench by sleeving the coil body around the core column; and forming a package structure to cover the magnetic base and the coil structure.

Abstract: An inductive device and a method of manufacturing the same are provided. The inductive device includes a magnetic base, a coil structure, and a package structure. The magnetic base includes a bottom plate, a core column, and a lateral wall defining a positioning trench. The coil structure includes a coil body, a first extending section, and a second extending section. The coil body disposed in the positioning trench surrounds the core column. The first extending section includes a first bent portion and a first terminal portion connected at a first connecting point. The second extending section includes a second bent portion and a second terminal portion connected at a second connecting point. A shortest distance between a first imaginary connection line defined between the first and second connecting points and a central axis of the core column is less than a minimum outer radius of the coil body.

Abstract: A laminated inductor includes a plurality of magnetic plates, each having a surface to which a high-permeability magnetic body is attached, and at least one spacer assembly interposed between the magnetic plates. The spacer assembly includes two magnetic boards having moderate magnetic permeability and a magnetic board having low magnetic permeability interposed between the two moderate-permeability magnetic boards. Both moderate-permeability and low-permeability boards are provided, at a surface of each board, with a magnetic body having high permeability. A magnetic top lid and a magnetic bottom lid are respectively set on outside surfaces of the topmost and bottommost ones of the magnetic plates. The high-permeability magnetic bodies mounted to the magnetic plates and the arrangement of the spacer assembly help improve the characteristic of DC superimposition of the laminated inductor thereby enhancing current endurance thereof.
