Mn-Zn Ferrite TP4K Material with Low Power Loss at High Temperature

Abstract

The Mn-Zn ferrite TP4K material was prepared by traditional oxide method, which has high saturation magnetic flux density and low power loss at high temperature. The Bs of the TP4K material is 535mT at room temperature, 430mT at 100°C, 350mT at 140°C; At temperature T=140°C, the power loss is lower than 340 kW/m3, which was measured under the frequency f=100kHz, the magnetization B=200mT.
