摘要： The present invention relates to a multilayer power inductor in which sheets are charged with a soft magnetic metal alloy powder having a shape optimized along a magnetic path, pattern circuits made from conductive materials are formed on the sheets, and via holes are formed through the sheets to easily connect pattern circuits. The power inductor of the present invention is manufactured by stacking the above-described sheets into multiple layers. The sheets of the inductor of the present invention are charged with soft magnetic metal powder having a high magnetization density, and fine gaps are distributed among the powder the shape of which is optimized along a magnetic path to ensure high current bias characteristics which allow the use of 1A to several tens of A without causing leakage flux, and ensure stable inductance to a high frequency domain of the 10MHz band. Further, the present invention is advantageous as it provides an inductor with a thin width, a large area, high inductance and high direct current bias characteristics.

摘要： In mobile communication terminals, there may be problems such as damage to humans by microwave leakage and the generation of microwave disturbance by radiation noise. Disclosed herein is a conductive thin film type microwave absorber with improved microwave absorption rate due to the formation of an impedance resistive film, comprising a microwave absorbing layer and a resistive film formed on a surface of the microwave absorbing layer wherein the microwave absorbing layer is composed of a magnetic composite material and dielectric material for reduction in the thickness of the microwave absorber, and the resistive film is capable of inducing impedance matching. Specifically, the conductive thin film type microwave absorber comprises: a microwave absorbing layer (1) having a thickness corresponding to ? of the wavelength (λ) of an incident microwave and composed of a magnetic composite material or ceramic ferroelectric material; a resistive film (2) formed on a microwave-incident face of the microwave absorbing layer (1) and having a surface resistance of 377±20 O/sq so as to induce impedance matching, the resistive film being composed of a conductive paste, a conductive polymer or a conductive oxide thin film; and a conductor layer (3) formed on a face opposite to the resistive film (2).
