Applications
>> 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
Features
>> 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℃
