Abstract

A pulse transformer having primary and secondary windings on separate insulating bobbins which are carried on the arms of a pair of U-shaped ferrite cores which provide a continuous magnetic path for coupling relatively high energy pulses. The bobbin and core assembly is assembled in and held together by a close fitting molded plastic housing which carries four pins to which the primary and secondary windings are attached. The connecting pins extend from a side of the housing which is open to receive the bobbin/core assembly and are adapted for printed circuit board mounting in which the board covers the housing opening so that the transformer is completely protected.
