[0002] E-type manganese-zinc ferrite core is a common magnetic component used to manufacture inductors, transformers and other magnetic devices. It is made of manganese-zinc ferrite material and has a specific shape and structure. E-type manganese-zinc ferrite core usually has a rectangular or square middle hollow structure, similar to the shape of the letter "E", hence the name E-type core. Its structure includes two parallel sides and a middle part connecting the two sides. The middle part can be hollow or filled or wrapped with other materials. The design and manufacture of the E-type manganese-zinc ferrite core is intended to provide low magnetic resistance, high magnetic permeability and good magnetic properties. It has excellent magnetic permeability and magnetic saturation characteristics and can be used to handle high-frequency and high-power applications. By winding the winding (coil) on the core, the functions of inductor and transformer can be realized. The E-type manganese-zinc ferrite core is widely used in various magnetic devices in electronic equipment, power systems, communication equipment, computers and other fields. Its characteristics include efficient energy transmission, low loss, stable magnetic properties and good temperature stability. However, in actual use, manganese-zinc ferrite cores with similar structures still have many defects, such as: when one side of the E-type manganese-zinc ferrite core body is damaged, it is not convenient to replace the E-type manganese-zinc ferrite core, and when assembling two E-type manganese-zinc ferrite cores, it is not convenient to install and fix the E-type manganese-zinc ferrite core, so it is necessary to design a manganese-zinc ferrite core. Utility Model Content
