Background
Magnetic core refers to a sintered magnetic metal oxide composed of various iron oxide mixtures. For example, manganese-zinc ferrite and nickel-zinc ferrite are typical magnetic core materials. The manganese-zinc ferrite has the characteristics of high magnetic permeability and high magnetic flux density, and has the characteristic of lower loss when the frequency is lower than 1 MHz. Nickel-zinc ferrite has characteristics of extremely high resistivity, low permeability of less than several hundred, etc., and also produces low loss at frequencies higher than 1MHz, etc. Ferrite cores are used in coils and transformers of various electronic devices, the structures of the cores in the industry are many, different structures and functions are different, manufacturers produce cores with different structures according to different requirements of customers, and even if the cores are of the same structure, slight differences can cause different functions, such as heat dissipation and shielding functions. According to the performance of various ferrite materials, magnetic cores which can be matched can be selected from different frequency ranges, and the power consumption and the temperature of the power ferrite material are in a negative relation, so that the requirement that the switching power supply transformer requires small heat emission can be met, and when the power ferrite material is in a strong magnetic field, the power loss is very small, and larger output power can be generated.
