5 General FAQ for Amorphous Magnetic Cores

1. Q: What are the main advantages of 1K107B amorphous magnetic ring compared with ferrite core? A: Amorphous core has much higher saturation flux density and better DC bias resistance. It can work at higher current without magnetic saturation, suitable for high‑power filtering scenarios.
2. Q: What should we pay attention to during processing amorphous magnetic ring? A: Amorphous material is sensitive to mechanical stress. Heavy impact, squeezing or strong bending will degrade its magnetic performance. Handle gently during assembly and winding.
3. Q: What is the operating temperature limit for 1K107B amorphous core? A: Normal working temperature is ‑50℃ to 150℃. Do not exceed crystallization temperature 510℃, otherwise the amorphous structure will be damaged and permanent performance failure occurs.
4. Q: Can amorphous magnetic rings replace ferrite cores directly in existing projects? A: Not direct replacement. Amorphous and ferrite differ in permeability, impedance and dimension. It needs re‑calculation on winding turns to match circuit requirements.
5. Q: Why will amorphous core produce noise in actual operation? A: It is mainly caused by magnetostriction effect under alternating magnetic field. Proper encapsulation or potting treatment can effectively reduce vibration and audible noise.
