1. Q: What is the normal working temperature range for 1K107B amorphous magnetic ring? A: Standard working temperature is ‑50℃ to 150℃. Long‑term operation shall not go beyond this interval to guarantee stable service life.
2. Q: Can amorphous magnetic rings be directly used to replace ferrite cores in existing circuits? A: Direct replacement is not recommended. Permeability, impedance and dimension parameters differ greatly. Winding turns need recalculation according to actual circuit requirements.
3. Q: Why does amorphous magnetic ring produce buzzing noise during operation? A: It is caused by magnetostriction effect under alternating magnetic field. Vibration generates audible noise. Potting, encapsulation or adding damping material can effectively reduce such noise.
4. Q: Does mechanical impact affect amorphous magnetic ring performance? A: Yes. Amorphous alloy is sensitive to mechanical stress. Heavy impact, squeezing, dropping or excessive clamping force will degrade magnetic performance permanently.
5. Q: Can we get samples of amorphous magnetic ring for performance testing? A: Yes, sample service is available for your circuit verification. Custom size and parameter requirements can also be discussed.
