1) high initial permeability, μ = 30000 ~ 80000, and the magnetic flux density and conductivity with temperature is very small;
2) very low core losses, and in the range of -40 ~ +120 ℃ does not change with temperature;
3) very high saturation flux density (BS = 1.2T), allows you to select a lower switching frequency, can reduce the switching power supply and EMI filter costs;
4) core using epoxy resin, high mechanical strength, no magnetostriction phenomenon, able to withstand strong vibrations;
5) can replace the conventional ferrite core to reduce the size of switching power supply, improve reliability.
