JFE Ferrite Group Mn-Zn ferrite cores are classified into four material grades according to different applications :

• Power Ferrite Material : Designed for low power-loss power supply applications.
• High-Frequency Ferrite Material : Designed for high-frequency, low power-loss power supply applications.
• High-Permeability Ferrite Material : Designed for EMI/EMC noise suppression and pulse transformer applications.
• High-Performance Ferrite Material : Suitable for high-frequency and high-performance applications, including EMI/EMC noise suppression.
