Power Inductor

Information

  • Metal Composite

    Depending on the body materials, power inductors are divided into ferrite inductors and metal composite inductors.
    The metal composite inductors have a high rated current and are very efficient.

    Application
    Smart Phones, DC-DC Converters for DSC, DVC, PDA, and Others

    Characteristics of Metal Magnet Winding Type

    Metal magnet winding-type inductors have high-efficiency and high-current (DC-bias) characteristics due to their optimal body material composition and coil.
    These inductors are recognized for their high capacity (4.7 μH).

    Superb Efficiency Characteristics

    If the power inductor efficiency is low, battery consumption increases. Efficiency test results show that power inductors are superior to ferrite winding-type inductors in terms of efficiency. Samsung has continuously developed and launched metal magnet power inductors with improved efficiency.
