摘要:	The core loss mechanism of low loss grade Mn-Zn ferrite in the frequency from 1MHz to 10MHz was investigated in order to find out the possibility of developing Mn-Zn ferrites to be used at such high frequency region. under the condition of f;B=25KHz.T, it was found that dielectric loss dominated the core loss at the frequency between 1.1 and 3MHz, while eddy current loss dominated the core loss at the frequency higher than 3MHz. It is suggested that decrease of grain boundary capacitance and increase of grain resistivity of the core mar be the suitable ways for the Mn-Zn ferrites to be used at such frequency region.
