  • Product description
  • Model number
  • Typical graph
  • Main application field

  • The company has developed a variety of serialized common mode inductor cores based on different application needs.

    The nanocrystalline common mode inductor core is divided into three series of products: 1K107F (high permeability), 1K107G (medium permeability), and 1K107H (low permeability).     

    Performance characteristics

    High saturation magnetic induction intensity, BS value of about 1.2T

    The hysteresis coefficient is extremely low, approaching 0

    High magnetic permeability, wide range of magnetic permeability, suitable for EMI filtering in different situations
