Technical Field

The invention relates to the technical field of magnetic cores, in particular to a combined type high-integration-level soft magnetic ferrite magnetic core.

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. The nickel-zinc ferrite has the characteristics of extremely high resistivity, low magnetic permeability of less than several hundred, and the like. Ferrite cores are used in coils and transformers for various electronic devices.
