SMD wire-wound power inductor with a plastic base, to achieve robust construction and higher inductance value. SDB none-shielded SMD power inductor has a simple structure, winding wire around a drum core without magnetic shielded ring core. Hence have a better price, a higher saturate current carry capacity, and a better quality factor. This SMD wire-wound power inductor is suitable for applications which not sensitive to EMI but need a high saturate current. Dimension is from 6mm to 13mm, and wide range of inductance value.
