What is a Power Inductor?
It's an inductor for power supplies and circuits, made from metal composite or ferrite materials. It is primarily used in circuits for converting a specific voltage into a required voltage, and serves to supply stable power to the IC. As the inductor is used in the power circuit, it is manufactured to maintain inductance when the current is applied and to have low resistance characteristics.

Metal Composite

The metal composite type is composed of metal powder-based body material and low-resistance Cu coil. It is divided into the thin-film type and the winding type, according to the coil manufacturing method. Samsung Electro-Mechanics continues to develop and launch high-efficiency products using metal composite materials.
