    Fe-based Amorphous Rectangular Cut Core for Sale | Toroidal ...
    Iron-based amorphous cores for smoothing filters are soft magnetic components produced by rapid solidification, offering high permeability, high saturation induction (

    T
    ), and low core loss, significantly improving efficiency in high-frequency applications. They serve as ideal, cost-effective, and energy-efficient alternatives to traditional silicon steel and ferrite cores in power supply filters, PFC inductors, and motor drives.
    Key Features and Advantages:
    • High Performance: Lower core losses (
      < 7 0
      %
      lower than silicon steel) and high resistivity result in superior efficiency.
    • DC Bias Characteristics: Excellent Anti-DC bias properties make them ideal for inductors carrying high direct currents.
    • Compact Design: High permeability (
      1 2 0
      - -
      1 2 0 0
      ) allows for fewer winding turns, reducing component size and weight.
    • Temperature Stability: High-temperature stability ensures stable performance in high-frequency, high-current environments.
    Primary Applications:
    • Smoothing Filters: Used in rectifier circuits and inverter outputs for filtering and reducing current harmonics.
    • PFC Inductors: Power Factor Correction boost inductors in high-power supplies.
    • Choke Coils: Differential mode chokes in Switch Mode Power Supplies (SMPS).
    • Industrial Electronics: Common in uninterrupted power supplies (UPS) and renewable energy systems.
    Material Composition:
    These cores are manufactured by cooling iron-based alloys—often with boron (

    ), silicon (

    . This prevents crystallization, resulting in a thin, glass-like ribbon structure with high flexibility in permeability, which can be tailored across a wide range (120–1200
