The efd frequency transformer ferrite core material as below


The core of ferrosilicon aluminum powder (Kool M Cores) consists of 9%Al, 5%Si and 85%Fe powder. It is mainly used as a substitute for iron powder core, and its loss is 80% lower than that of iron powder core. The saturation magnetic sense is around 1.05T. Magnetic permeability ranges from 26 to 125. The magnetostrictive coefficient is close to 0, and there is no noise when working at different frequencies. DC bias capability is higher than MPP. Has the best performance ratio. It is mainly used in ac inductor, output inductor, line filter and power factor correction circuit. Sometimes it can replace air gap ferrite as core of transformer.


Ferrites, a ferrite with Fe2O3 as its main component, were made by powder metallurgy. There are mn-zn, cu-zn, ni-zn and other types, among which mn-zn ferrite has the largest yield and dosage, and mn-zn ferrite has a low resistivity, ranging from 1 to 10 ohm-meters, generally used at frequencies below 100kHZ. The resistivity of cu-zn and ni-zn ferrite is 102 ~ 104 ohm-meters, and the loss is small in the radio frequency range of 100kHz ~ 10 MHZ. The magnetic core has various shapes, including E, I, U, EC, ETD, square (RM, EP, PQ), can (PC, RS, DS) and circle.
