Nanocrystalline Transformer Core has very high permeability, high saturation induction, low coercivity, low core loss. Suitable for high frequency transformer of inverter welding equipment, solar inverter, and high power transformer in Kw range.
Material: Fe-based Nanocrystalline core
Saturation flux density induction: 1.25T
Permeability @ 10KHz: > 20000
Curie temperature(℃): 560
Stacking factor: 0.78
Saturation magnetostriction(*10^-6): <2
Resistivity (μΩ.cm): 90
Ribbon thickness: 25μm
Core shapes: Troidal core
High saturation flux density - you can reduce volume of transformers vs tranditional Ferrite
High permeability - improve efficiency,lower exciting power and reduce copper loss
Low coercivity and Low core loss - low temperature rise
Excellent thermal stability - working temperature of -40 - 130℃
>> Inverter welding machines
>> Electrolytic plating power supplies
>> High Power Laser power supplies
>> Communication, high-speed railway power supplies
>> High frequency heating systems
>> High frequency and high power switched mode power supply
