FAQ
Q: What is the difference between NiZn ferrite and MnZn ferrite cores?
A: NiZn ferrite has significantly higher electrical resistivity (~10⁶ Ω·m vs MnZn ~10²–10³ Ω·m) and higher Curie temperature, resulting in much lower high-frequency losses. It is suitable for high-frequency applications above 1 MHz. MnZn ferrite offers higher permeability and is better suited for low-frequency (<1 MHz), high-power applications.
Q: What is the saturation flux density (Bs) of NiZn ferrite cores?
A: The saturation flux density reaches up to 0.5T, ensuring stable performance and reduced risk of saturation under higher current conditions.
Q: What are the advantages of NiZn ferrite cores in DC-DC converters?
A: NiZn ferrite enables higher switching frequencies, which significantly reduces transformer size and weight while improving power density in modern DC-DC converters.
Q: Why is electrical resistivity important for NiZn ferrite cores?
A: High resistivity (up to ~10⁶ Ω·m) minimizes eddy current losses, which is the key reason NiZn ferrite performs significantly better than MnZn ferrite at high frequencies.
