With the development of 5G communication technology and the widespread commercial use of the third-generation wide bandgap semiconductors, the power electronic devices with higher frequency, miniaturization and higher energy efficiency become popular. MnZn ferrite as a high-frequency soft magnetic materials of power electronic devices has attracted attention recently. This review introduced the latest research progress on high frequency MnZn ferrites, including the realization of characteristics of high frequency, wide temperature and low loss through the main component design, additive regulation and low temperature sintering process. This review also represented the stress sensitivity of power loss in the high frequency MnZn ferrite. Somefurther researches on the mechanism of high frequency power loss could accelerate the development and application of low core loss high-frequency MnZn ferrite in this decade.
