Abstract
A method for preparing a power inductor includes the following steps A to E: A: preparing a composite wire; B: winding the composite wire according to a predetermined shape and a predetermined coil quantity, so as to form coils; C: placing the coils into a mold cavity, adding metal soft magnetic powder to the mold cavity, and pressing the metal soft magnetic powder and the coils to form a base comprising the coils; D: performing sintering treatment on the base; and E: plating two terminal electrodes on two ends of the base to form the power inductor.
