1. The inductor structure with one winding coil covered inside through the powder metallurgy technique comprises one coil and plural metal particle, which have the following features:
- the repeatedly winded coil is one winding coil with plural terminals extended toward one side and the winded portion covered within plural metal particles via one die-casting process and then high-temperature sintering, and has its extended terminals be flat and then bended toward 90 degrees with one punching fixture as a one-piece Surface Mount Device inductor providing stable inductance and dramatically reducing costs and manufacture steps.

Abstract
The invention of one inductor structure comprises one coil, which has one winding coil together with two extended terminals, and plural metal particles with magnetism at least where the winding coil inside plural metal particles is casted and sintered by the powder metallurgy technique and two extended terminals are flat and bended toward 90 degrees in automated punching equipment to become a one-piece chip inductor with costs & fabrication steps dramatically reduced and stable inductance provided.
