Abstract
The invention relates to the field of inductors, in particular to a frame of an ultrathin inductor and a production method of the ultrathin inductor. The frame of the ultrathin inductor comprises a frame body having an inner accommodating cavity and a winding magnetic core post nested in the accommodating cavity of the frame body. A first tray is disposed at the bottom end of the winding magnetic core post. Since the magnetic frame body is sleeved outside the winding magnetic core post, the magnetic flux in coils is greatly increased while the number of coils is fixed; thus, the ultrathin inductor is simple in structure, the size the ultrathin inductor is reduced effectively while the height is decreased effectively, and the inductor made with the inductor frame can be applied to smaller electronic products. In addition, the frame body fits with lead heads, so that automatic welding is allowed with SMT welders, the labor cost is greatly reduced, and production efficiency is improved; the frame body is made of magnetic material, so that magnetic radiation of the inductor body is greatly reduced and the problem of EMI of the inductor body upon the circuit is solved effectively.
