One、Ferrite cores are mainly made of iron(Fe)，manganese(Mn)，And zinc(Zn)3The composition of three metal elements，It is usually called Mn Zn ferrite。The annular ferrite core has no air gap，And the cross-sectional area is the same，So the magnetic effect is very high。
Two、An inductor or transformer can be made by winding a coil on a ferrite core，They are widely used in instruments，Communication equipment and household appliances。 There are many kinds of ferrite cores，There are also many geometric shapes，It is cylindrical、I-shape、Hat shape、Single hole、Double hole、Four holes、 U shape、Can shape、 E shape、 EI shape， EC shape、 RM shape， PQ shape、 EP shape，See the attached figure。Each type of core has its own series，For users to choose。
Three、Ferrite cores have a wide range of choices，According to different magnetic parameters，To choose different materials and shapes due to the low magnetic loss at high frequencies，They are widely used in switching mode power supply(SMPS)，radio frequency(RF)Transformers and inductors。Ferrite cores of various shapes and sizes are used in high frequency power supply and inductors in high quality communication market，pulse transformer，High frequency transformer，And noise filter, etc。Ferrite is characterized by high permeability，Good temperature characteristics，And low decay rate。
