This paper presents SMD inductors composed of soft-magnetic metal powder compacts based on newly developed materials and processes. High saturation magnetization of the core materials results in high DC-Bias characteristics and downsizing inductors, which can never be achieved by conventional ferrite core inductors. These SMD inductors can realize high efficiency in a circuit due to low loss characteristics in comparison with metal composite type inductors as well as ferrite inductors.
