Brief Introduction Of Ferrite Core
Ferrite core is mainly composed of iron (Fe), manganese (Mn), and zinc (Zn) three metal elements, commonly known as manganese-zinc ferrite. Because the annular ferrite core has no air gap and the cross section area is uniform, the magnetic effect is very high.
Ferrite rings have a wide range of sizes, depending on the material of the rings, and can be easily wound with different coatings to increase breakdown voltage.
What is a ferrite core?
Ferrite cores are dense, homogeneous ceramic structures made by mixing iron oxide (Fe2O3) with oxides or carbonates of one or more metals such as manganese, zinc, nickel, or magnesium. They are pressed, then fired in a kiln to 1300o C, and machined as needed to meet various operational requirements. Ferrites have an advantage over other types of magnetic materials due to their high electrical resistivity and low eddy current losses over a wide frequency range. These characteristics, along with high permeability, make ferrite ideal for use in applications such as high frequency transformers, wide band transformers, adjustable inductors and other high frequency circuitry from 10 kHz to 50 MHz. Ferrites are available in a wide variety of materials and geometries allowing for flexibility in magnetics and mechanical parameters.

Ferrite core is made of dense homogeneous ceramic structure Nonmetallic Magnetic materials, with low coercivity, also known as soft magnetic ferrite. It consists of iron oxide (Fe2O3) and an oxide or carbonate compound of one or more other metals (e.g., manganese, zinc, nickel, magnesium). Ferrite material is pressed, then sintered at 1300 C, and finally processed by machine to meet the application requirements of the finished core. Compared with other types of magnetic materials, ferrite has the advantages of high permeability, high resistance and low eddy current loss in a wide range of frequencies. These material properties make ferrites ideal for manufacturing high-frequency transformers, broadband transformers, adjustable inductors, and other high-frequency circuits ranging from 10 kHz to 50 MHz.
