5 General FAQ for Amorphous Magnetic Cores

Q: What is an amorphous magnetic ring?
A: An amorphous magnetic ring is produced from high-quality amorphous alloy via rapid quenching molding technology. Its unique disordered atomic structure enables far better comprehensive magnetic performance than traditional ferrite magnetic cores.

Q: What are the main advantages of 1K107B amorphous magnetic cores?
A: The 1K107B amorphous material features ultra-high initial permeability, excellent saturation flux density, outstanding DC bias resistance and a wide temperature adaptation range. It is specially optimized for high-power power supply equipment to eliminate common-mode noise and improve EMC performance.

Q: What are the key differences between amorphous cores and ferrite magnetic rings?
A: Amorphous cores have significantly higher saturation flux density and stronger resistance to DC current saturation, making them suitable for high-current and high-power scenarios. In contrast, ferrite cores offer higher cost performance and are more applicable for medium and low-power filtering applications.

Q: Why can amorphous magnetic cores resist saturation under high DC current?
A: Thanks to its superior saturation magnetic flux density, the amorphous core can retain stable permeability even with superimposed DC current. It is not prone to magnetic saturation, which makes it the optimal choice for manufacturing high-power common mode chokes.

Q: What happens if the amorphous core exceeds its crystallization temperature?
A: Once the operating temperature surpasses 510℃ (the crystallization threshold), the internal amorphous atomic structure will permanently convert to crystalline structure. This will cause irreversible damage to the core’s magnetic performance and completely fail its filtering function.
