Abstract

A composite magnetic material composition includes: soft magnetic material powders; permanent magnet material powders; and a binder. The material made from this composition magnetic material composition has a relative magnetic permeability of said from 1 to 100. A magnetic core fabricated using this composite magnetic material composition is magnetized, after its fabrication, and a permanent magnetic field is retained in it, regardless of the operation status of the magnetic core. The magnetic flux density of the permanent magnetic field in this magnetic core is in the range of 10 to 2000 gauss. Magnetic components comprising this magnetic core have a higher saturation current.

Description

technical field [0001] The invention relates to a magnetic material composition and magnetic components including the same, more specifically, to a composite magnetic material composition and magnetic components with increased saturation current. Background technique [0002] For surface mount magnetic components in electronic equipment such as computing equipment, entertainment equipment, and automotive equipment, reducing the area occupied by the circuit board to provide increasingly miniaturized magnetic components is the trend but is challenging. . By reducing the occupied area of ​​components on the circuit board, the size of the circuit board components of the electronic device can be reduced, and thus the number of components on the circuit board can be increased, thereby improving the power density of the electronic device and reducing the manufacturing cost of the electronic device. Reducing design and manufacturing costs is very important for electronic component ...
