摘要： Disclosed herein is a surface mount type power inductor which has an outer magnetic capsule integrated with a coil-wound inner core, and which thus has no air gap between the outer magnetic capsule and the inner core, and can maintain a large inductance L in a high current condition. In the inductor, a coil is wound a predetermined number of turns around the inner core formed from ferrite or magnetic metal. An outer magnetic capsule, molded from a magnetic powder, an insulation filler, a binder, and a lubricant, is provided to cover the inner core and the coil.
