Abstract

Disclosed is a choke and its manufacturing method, which uses metallic wire as base material to form a helical coil by spiral winding, the formed helical coil being then placed into a mold and filling with magnetic powders to completely encapsulate the helical coil, which is subject to a molding step to form a encapsulant of the encapsulated helical coil without air gaps; wherein the metallic wire used for the spiral coil is divided, prior to winding, into front/rear sections or upper/lower pieces, such that the front/rear sections or the upper/lower pieces of metallic wire helically winds from the separate part to different directions to obtain the completely wound helical coil with its wire-ends located outside the helical coil.
