Ferrite core is a high-frequency magnetic material, mainly made of iron oxide mixed with other metal oxides (such as manganese, zinc, etc.) and then fired. It has the characteristics of high magnetic permeability and low loss, and is widely used in electronic equipment. Ferrite cores can be made into various shapes and sizes to meet different application requirements, such as transformers, inductors, filters, etc. In high-frequency environments, ferrite cores can effectively transmit and convert electromagnetic energy while reducing energy loss and improving the efficiency and performance of equipment. In addition, ferrite cores also have good temperature stability and mechanical strength, and can maintain stable performance in various harsh environments.
