NiZn Ferrite Core ✉ generally has low permeability μ ratio, fine and small grains, porous structure, often brown, above 1M Hz, because of its porosity and high resistivity, NiZn ferrite is much better than MnZn system and becomes the best soft magnetic material in high frequency applications. Its resistivity ρ up to 108Ω·m, high frequency loss is small, especially suitable for high frequency 1 ~ 300M Hz; In addition, the Curie temperature of NiZn is higher than that of MnZn,Bs is as high as 0. 5T, and Hc is as low as 10A/ m, which is suitable for various inductors, mid-circle transformers, filtering coils and chokes. Nickel-zinc high frequency ferrite material with wide bandwidth and low transmission loss is often used in high frequency anti-electromagnetic interference and high frequency power and anti-interference integrated surface mounted devices, as anti-electromagnetic interference (EMI) and radio frequency interference (RFI) magnetic core. Nickel-zinc power ferrites can be made into RF broadband devices, which can realize the energy transmission and impedance conversion of RF signals in the wide band range. The lower limit of frequency is several thousand Hertz, and the upper limit of frequency can reach several thousand megahertz. The nickel zinc power ferrite material used in DC2DC converter can increase the frequency of switching power supply and further reduce the volume and weight of electronic transformer.
