Application Fields:
• Transformer cores for high frequency switch mode power supplies
• Current transformer cores for electric industry
• Transformer cores for ground-fault-interrupters
• Cores for filters, storage inductors, and reactors
• EMC common mode chokes
• Sensor cores
• Cores for saturable reactors, magnetic amplifiers, beads, and pulse compressors
Characteristics:
• High saturate induction—minimize transformer volume
• High permeability and low coercivity—promote efficiency of transformers and reduce distributional capacitance
• Low core loss—minimize temperature rise of transformers
• Excellent stability—with the highest serving temperature of 130℃for long time
• Relatively low cost compared to permalloys
