Inductor

Inductors are surface-mounting–type parts made through a multilayer process, a winding process, and a thin film process. They are passive components that display inductance.
They are mainly used for the smoothing of power circuits, the impedance matching of RF circuits, the L-C filters, and the LC resonant circuits.

Power Inductor

Power inductors are used for the purpose of smoothing in PM (Power Management) ICs and DC-DC converters that require high-rated current and low RDC (Resistance). SEMCO owns a product lineup of low-current multilayer-type inductors, high-current/high-efficiency HEPI (High Efficiency Power Inductors) and high current/high capacity winding-type inductors.

Why Samsung

Classification of Power Inductors

Depending on the body materials, power inductors are divided into ferrite inductors and metal composite inductors. The metal composite inductors are high in rated current and superb in efficiency.

Power Inductor Classification

Characteristics of Metal Magnet Thin Film Type

Materials with lower core loss and internal electrodes (coils) with a higher A/R ratio are used. These products show high-efficiency characteristics and have very high characteristics of rated current (DC-bias) compared with multilayer-type products.

Metal Magnet Thin Film Type

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.

Sectional View

Winding Type

Winding-type inductors are made by winding coils in “α” shape and the surrounding magnet around them.

Winding Type Sectional View

Thin Film Type

Thin film–type inductors are made by plating coils on substrates and surrounding them with magnets.

Thin Film Type Sectional View

Multilayer Type

Multilayer-type inductors are made by printing electrodes on magnet sheets and stacking the layers of magnet sheets. Magnet sheet covers are placed on the top and bottom surfaces.

Line-Up

A lineup ranging 2520–1608 is available, and the products that are reduced in size and enhanced in rated current have been added continuously.
