What are Nanocrystalline Magnetic Materials?
Nanocrystalline are soft magnetic materials that have nano-sized crystals in amorphous alloys.
Nanocrystalline alloys have higher relative permeability and saturation magnetic flux density than general ferrite materials. They are suitable for Common Mode Choke Coils because they are small and can reach high inductance (Table 1). They are sometimes called "nanocrystal" using the Japanese reading of the English name(Nanocrystalline).
Our lineup of Common Mode Choke Coils using Nanocrystalline materials contribute to the miniaturization and weight reduction of sets.
