Inductor structure

Abstract

An inductor structure includes a powder core sinter, a coil, and a coating body. The powder core sinter includes a base and a convex column. The convex column is arranged on the base, so that the powder core sinter is in inverse T-shaped. An accommodation space is formed on the base and around the convex column. The coil includes a coiling body wrapping the convex column and being arranged in the accommodation space. The coiling body includes two electrode pins extended to lateral sides of the base. The coating body includes a fillister in inverse T-shaped. The fillister accommodates the powder core sinter and the coil. The coating body fully covers the powder core sinter and the coil except the two electrode pins extended outside of the coating body. The inductor structure has high current resistance and high heat resistance, and avoids the current leakage phenomenon.
