Technology

King Magnetics has developed one of the technology of amorphous and nanocrystalline materials, cores and components. We keep the creative technology, which is the key to produce the cores. We focus on high performance nanocrystalline core for common mode choke, nanocrystalline core for high frequency transformer and nanocrystalline C cores.

Nanocrystalline Material Characteristics

Nanocrystalline Material Characteristics

Fe-based nanocrystalline material with composition of mostly Fe with Cu,Nb,Si,B, which first by rapid quenching technology to form amorphous ribbon, then by crystalline heat treatment to gain fine grains with nano scale. Through this revolutionary process, we can get superior magnetic properties with high saturation flux density, high initial permeability, low coercivity, low core loss. Nanocrystalline material is an environmental protection, green, low carbon,high efficiency new magnetic material.

How does nanocrystalline common mode choke work?

How does nanocrystalline common mode choke work?

Common mode choke is an inductor has two windings. Two windings in the same direction when in or out. Load current produces load magnetic field which will cancel each other, so the choke will not affect the load current. While common mode current will produce magnetic field will strong each other, that is a larger impandence will occur in the core, the common mode current then being blocked.
