Amorphous and nanocrystalline technology is a modern advanced science and technology. It is a revolution in the history of metallurgy. As a new type of soft magnetic material, it has been widely used in high performance magnetic cores, inductors, transformers and so on. A series of amorphous and nanocrystalline cores have been developed for common mode inductors.

Nanocrystalline magnetic core with high magnetic permeability, wide frequency characteristics, until 30MHz still has high permeability and high frequency. Very suitable for EMC filters, common mode inductors to suppress common mode noise. Compared with the traditional soft magnetic materials, such as ferrite cores, the advantages of the nanocrystalline magnetic core are obvious, high inductance, good filtering effect, small volume, less copper wire turns, high efficiency and energy saving.

The Curie temperature of the nanocrystalline magnetic core is as high as 560 DEG C, which is much higher than that of the traditional ferrite core, which is only about 200 DEG C, and the high Curie temperature makes the nanocrystalline magnetic core have very high thermal stability, and can continuously work at a temperature of 120 DEG C.

Nanocrystalline core has become the preferred material of common mode inductor core.
