とする増幅器用絶縁トランス。 A coil bobbin has an internal flange with multiple slits attached to both sides of the inside of the flange. A small gap is created between the flange and the internal flange, and an insulating tape is wound between the layers of the winding wire wound around the coil bobbin. Perform the required winding, pass the beginning and end of each winding through separate slits in the inner collar at both ends, maintain the distance between the windings, and pass through the groove between the inner collar and the bottom surface of the coil bobbin. The end of the winding is connected to the installed board terminal, and the magnetic core is assembled into the coil bobbin with the wire wound so as to form a closed magnetic circuit to form a transformer.The entire transformer is then electrically insulated by resin molding using vacuum impregnation. An isolation transformer for amplifiers characterized by a multilayer structure.
