In summary, Samsung 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). The 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. 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 in efficiency. 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. Samsung has continuously developed and launched metal magnet power inductors with improved efficiency.
