Lower losses, smaller size and reduced weight
The losses of a Nanocrystalline core can be up to two-thirds less than an equivalent Nickel Supermalloy core and up to 80% less than for toroid geometries. Less power is dissipated by the transformer (or inductor) and means the size of cooling components can be reduced.
Ease of switch over from other materials
Nanocrystalline can be formed into any shape and therefore offers a drop-in replacement for existing cores manufactured from other materials, such as Supermalloy or ferrite.
Nanocrystalline v Supermalloy
Nanocrystalline material is more suitable than Supermalloy in applications such as high frequency/broadband transformers, broadband current sensors, high frequency filter chokes and pulse transformers because nanocrystalline offers:
- High permeability over a broad frequency range
- High saturation flux density
- Low losses
