Manufacturing method for realizing high-performance surface-mounted inductor with small and thin shape

The invention discloses a manufacturing method of a small and thin surface-mounted inductor capable of realizing high performance, and relates to the technical field of manufacturing methods of surface-mounted inductors, comprising the following steps of: selecting a flat coil body for three-dimensional winding; the coil body is heated to form a hollow coil, and the tail end of the coil body is bent at a right angle; the coil body is inserted into the T-shaped core and then integrally placed into the forming die, the I-shaped core covers the forming die, and the I-shaped core is processed into a formed body in an independent pressure applying mode or a pressure applying and heating mode; the tail end of the coil body is exposed out of the bottom surface of the forming body, and an external electrode is formed on the section of the tail end exposed out of the bottom surface of the forming body, so that the surface-mounted inductor is formed, a thinned inductor capable of reducing Rdc can be provided, and the p
