FAQ

Q1: What is the difference between Mn‑Zn and Ni‑Zn ferrite rings? A: Mn‑Zn ferrite features high permeability and works better for low‑to‑medium frequency interference. Ni‑Zn ferrite fits higher‑frequency scenarios. Please select material grade according to your operating frequency.

Q2: How to choose the correct size of ferrite toroidal core? A: Confirm outer diameter, inner diameter and thickness. Inner diameter needs enough space for wire passing or winding. Also consider operating current and required impedance value for your circuit.

Q3: What affects the anti‑interference effect of magnetic rings? A: Material permeability, winding turns, working frequency and installation position will influence noise suppression performance. More winding turns normally bring better low‑frequency suppression.

Q4: Can ferrite magnetic rings work at high temperature? A: The maximum working temperature is limited by Curie temperature. Magnetic performance will drop sharply once exceeding Curie temperature. Avoid continuous operation above its rated temperature.

Q5: Are custom sizes and material grades available? A: Yes. Custom ferrite cores with special dimensions or material parameters are supported. Please provide detailed specification requirements for quotation.
