brief introduction

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.

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.
