Product Description
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

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
