Fe based soft magnetic alloy, its manufacturing method and magnetic component using the same

摘要

An Fe-based soft magnetic alloy is provided. An Fe-based soft magnetic alloy according to an embodiment of the present invention is represented by an empirical formula FeaBbCcCud, where a, b, c, and d are at% (atomic percent) of the element, and 78.5 ≦ a ≦ 86, 13.5 ≦ b + c ≦ 21, 0.5 ≦ d ≦ 1.5. According to this, with high saturation magnetic flux density, excellent high frequency characteristics, and low coercive force, it is very easy to develop applications as high performance / high efficiency small / light weight parts. In addition, the present invention has a very low manufacturing cost, and the components contained in the alloy are easily controlled in the manufacturing process of the alloy, making it easy to manufacture the alloy and enabling mass production. It can be widely applied as magnetic parts of electrical and electronic equipment such as high power laser, high frequency power supply, high speed pulse generator, SMPS, high frequency filter, low loss high frequency transformer, high speed switch, wireless power transmission, electromagnetic wave shielding.
