Technology

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.

Calculate nanocrystalline core just the same as other cores, like ferrite, sendust core, MPP core or High flux core.

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.

When designing amorphous and nanocrystalline cores, need to calculate the weight of nanocrystalline and amorphous cores,input the follow parameters of the core and click “Calculate”, just feel free to use, and make sure to input the bare core dimensions. 

King Magnetics has advanced technology of amorphous and nanocrystalline materials, cores and components. Let is find out how amorphous and nanocrystalline cores are made.
