Winding type integrally-formed coupling inductor

The invention discloses a winding type integrally-formed coupling inductor which comprises a packaging magnet, a first coil, a second coil, a first electrode, a second electrode, a third electrode and a fourth electrode. The first coil and the second coil are arranged in the packaging magnet. The first electrode, the second electrode, the third electrode and the fourth electrode are arranged at the four corners of the surface of the magnet respectively. The first coil is arranged on the outer side of the second coil, two leads of the first coil are connected with the first electrode and the second electrode respectively, and two leads of the second coil are connected with the third electrode and the fourth electrode respectively; polysulfone resin coatings are arranged on the surfaces of the first coil and the second coil; the packaging magnet is made of a powdery amorphous material, iron powder plated with a silicon layer on the surface and an adhesive through hot press molding and then annealing at the temp
