Core Loss VS Magnetic Induction Density

• High saturate induction reduce volume of transformers
• High permeability and low coercivity improve efficiency
• lower exciting power and reduce copper loss
• Low core loss reduce temperature rise of transformers
• Excellent thermal stability with the serving temperature of -55°C-130°C for long time
• LOWEST  CORE  LOSS :P <6W/Kg @ 20KHz,0.5T , P<9W/Kg @ 20KHz, 1T, P<5W/Kg @ 35KHz,0.5T, P<14W/Kg @ 35KHz,1T
•  High Bs =1.4T ,  low Br <10mT,  Low Hc <1A/m , u=10000
