[0002] As we all know, a magnetic core refers to a sintered magnetic metal oxide composed of a mixture of various iron oxides. It has the characteristics of high magnetic permeability and high magnetic flux density, as well as low loss. In addition, due to the extremely high resistivity and low magnetic permeability of less than a few hundred, ferrite cores are widely used in coils and transformers of various electronic devices.
[0003] When manually winding the coil on the annular core, the staff lacks precision in manual operation, which easily causes the problem of uneven coil. The uneven coil will cause uneven magnetic field distribution, which will affect the electromagnetic performance. For this reason, we propose an integrated ferrite core.
