Main Difference of Nanocrystalline Core, Amorphous Core and Ferrite Core
- Saturation Magnetic Flux Density: Amorphous core (1.5T) > Nanocrystalline core (1.2T) > Ferrite core (0.5T). The amorphous core has the strongest anti-saturation capability, while the ferrite core is prone to saturation.
- Permeability: Nanocrystalline core > Amorphous core > Ferrite core. The nanocrystalline core has the highest permeability, making it suitable for high-sensitivity inductors/transformers.
- High-Frequency Loss: Nanocrystalline core < Amorphous core < Ferrite core. The nanocrystalline core has the lowest medium and high-frequency loss, while the ferrite core still has advantages at ultra-high frequencies (MHz level).
- Temperature Stability: Nanocrystalline core (570℃) > Amorphous core（410℃） > Ferrite core (250℃). The nanocrystalline core has the optimal high-temperature performance, while the ferrite core is prone to demagnetization at high temperatures.
