This small PCB is designed for some common applications using a few of our pin compatible transformer models. Typical applications would be galvanic isolation or balanced-to-unbalanced conversion. The PCB can be used in combination with a DIN housing, or can be screw mounted without any housing.In addition to the transformer, the board has two holes for mounting screws (3,2mm) and positions for screw or spring terminals.
