Why We Use Nanocrystalline Core For Electronic Components?


Nanocrystalline is a soft magnetic material composed of Fe, Si, B, and has been widely used in the field of electronic component manufacturing. Its excellent characteristics such as high magnetic permeability can lower the magnetic core loss of the transformer, and at the same time greatly reduce the size and weight of the components.

Lower loss, smaller and lighter

The loss of nanocrystalline cores is only 30% of permalloy cores, which is 70%-80% lower than ferrite cores. Therefore, transformers and inductors consume less power and are smaller in size, so nanocrystalline cores can be applied to more sophisticated instruments and equipment, which is not possible with ferrite cores.

Easy to process and manufacture

Nanocrystalline material can be made into different shape, powder and spray ribbon are common, so nanocrystalline is an excellent material to alternative other materials (silicon steel or ferrite). Nanocrystalline ribbons can be used to make toroidal core or c cores, and the size of the magnetic core can be controlled more accurately by increasing or reducing the number of winding turns of the ribbon.

Nanocrystalline vs Ferrite

In today's trend of high-frequency components, nanocrystalline materials are more suitable than ferrite or silicon steel in applications such as transformers, current sensors, inverter, inductors, cores and coils. Its advantages are mainly reflected in the following aspects:

1. High permeability in a wide frequency range,

2. High saturation magnetic flux density,

3. Low loss.
