Today I mainly share with you new energy and new materials - ferrosilicon magnetic core, I hope to help you with your use.

　　New energy materials refer to the key materials used in the transformation and utilization of new energy and the development of new energy technology. Ferrosilicon aluminum powder core is a kind of soft magnetic material, which has high saturation magnetic induction, good high frequency magnetic properties, low loss, low cost and other characteristics, and has been widely used.

　　Soft magnetic materials are those that are easily magnetized and can be magnetized repeatedly, but when the magnetic field is removed, the magnetism is lost. The characteristics of this kind of material are: high permeability (μ=B/H), that is, it is easily magnetized in the magnetic field, and quickly reach a high magnetization; But when the magnetic field is gone, its remanence is very small. This material is widely used in electronics for high frequency technology. Such as magnetic core, magnetic head, memory core; In strong current technology can be used to make transformers, switching relays and so on.

　　Commonly used magnetic powder core are: iron powder core, Permo alloy powder core, iron silicon aluminum powder core three.

　　The effective permeability of magnetic core μe and inductance are calculated as: μe = DL/4N2S × 109

　　Where, D is the average diameter of the magnetic core (cm), L is the inductance (share), N is the number of winding turns, and S is the effective cross-sectional area of the magnetic core (cm2).

　　What is iron silicon aluminum? Simply put, it is composed of aluminum, silicon and iron, it has quite high B ** x(1050tM), its magnetic core loss is much lower than the iron core and high flux, has low magnetosteric (low noise), is a low-cost energy storage material, no thermal aging, can be used to replace the iron core, the performance is very stable at high temperature.

　　Characteristics: Appropriate cost, low loss, high saturation, low magnetostriction, no thermal aging, soft saturation.

　　There are six kinds of permeability: 26μ, 40μ, 60μ, 75μ, 90μ and 125μ; There are ring type, E type, square type, cylindrical type and other shapes. Applications include power factor correction chokes, boost/step-down regulators, DC output inductors and regression transformers. It is the output choke of switching power supply, PFC inductor and resonant inductor.. The best choice, has better performance price ratio.
