Five General FAQ for Ferrite Cores

Q: What factor mainly affects the noise suppression performance of ferrite core?

A: Material permeability, working frequency range, core dimension and winding turns will directly influence its noise suppression effect.

Q: What is the difference between Mn‑Zn ferrite and Ni‑Zn ferrite magnetic ring?

A: Mn‑Zn ferrite applies for low‑to‑medium frequency with high permeability. Ni‑Zn ferrite fits for high‑frequency scenario with high resistance.

Q: Will high working temperature damage ferrite core?

A: Working temperature shall stay below Curie temperature. Once exceeding Curie point, the ferrite will lose its magnetic property temporarily.

Q: Can I get custom ferrite core samples before bulk order?

A: Yes, samples can be provided for performance testing. Custom size and material are available upon request.

Q: Why does the same model ferrite core have different impedance data?

A: Impedance changes with testing frequency. Test under different frequency points will get different impedance results.
