Comparison of magnetic ring inductance of ferrosilicon and ferrite materials


The difference in magnetic cores leads to different characteristics of the magnetic loop inductance, and the application will be different. What is the difference between the ferrosilicon magnetic ring inductance and the common ferrite magnetic ring inductance? Let Xiaobian give you an analysis:


1, iron silicon aluminum magnetic ring inductance

The loss is lower than that of the iron powder core, and the good DC biasing characteristics are between the iron powder core and the iron nickel molybdenum (MPP) magnetic powder core.


2, nickel-zinc ferrite magnetic ring inductance

Nickel-zinc ferrite has low magnetic permeability and high resistivity for applications ranging from 2MHz to hundreds of megahertz


3, Mn-Zn ferrite magnetic ring inductance

The manganese-zinc material has a high magnetic permeability. MnZn ferrite can be used in applications where the operating frequency is below 5MHz. Nickel-zinc ferrite has a high resistivity and can be used in the frequency range of 2MHz to hundreds of megahertz.

It is well known that except for common mode inductors, the impedance of manganese-zinc materials is the best choice for applications below 70MHz, and nickel-zinc materials are recommended for applications from 70MHz to hundreds of gigahertz.
