PC40 ferrite powder is same as our TP40 ferrite powder. TP40 is a kind of power of MnZn ferrite powder, which material initial permeability is 2300±25%. Compared with PC30 material in the early market, the magnetic core of TP40 material can provide lower power loss. Under the high temperature point of 100℃, the loss of the material can be as low as 450 mW/cm³. The lower high temperature power loss makes the inductance transformer made of TP40 material suitable for power supply equipment with higher operating temperature. Under the high temperature working environment, it effectively reduce the heat output of the product, so as to more effectively protect the surrounding electronic components and power supply equipment, extend the service life of the equipment. It is the most widely used ferrite material in the market at present. It is suitable for making ferrite magnetic core of various shapes and widely used in all kinds of inductor and switching power transformer, pulse transformer, main power transformer, auxiliary power transformer and driver transformer.
