- Medical power and high‑reliability power electronic circuits
5 General FAQ for Amorphous Magnetic Cores
- Q: What is amorphous magnetic ring? A: Amorphous magnetic ring is made of amorphous alloy material. It forms disordered atomic structure through rapid quenching technology, delivering superior magnetic performance compared with conventional ferrite cores.
- Q: What are the core advantages of 1K107B amorphous magnetic core? A: 1K107B features high initial permeability, ultra‑high saturation flux density, great anti‑DC bias ability and wide working temperature range, mainly used for common‑mode noise suppression in high‑power power supplies.
- Q: What is the main difference between amorphous core and ferrite magnetic ring? A: Amorphous core owns much higher saturation flux density and better DC bias resistance for high‑current conditions. Ferrite cores are more cost‑effective and fit for medium‑low power filtering scenarios.
- Q: Why can amorphous core withstand higher DC current without saturation? A: It has high saturation magnetic flux density. Under superimposed DC current, it can maintain valid permeability and will not saturate easily, which is its key advantage for high‑power common mode chokes.
- Q: What damage will happen if amorphous core exceeds crystallization temperature? A: Once temperature exceeds 510℃ crystallization point, amorphous atomic structure will transform into crystalline state. Its excellent magnetic properties will suffer permanent irreversible damage.
