ABSTRACT:
A miniature high frequency power transformer comprises first and second "E" shaped ferrite core halves surrounding mating inner and outer modular transformer bobbins having formed thereon respectively the primary and secondary windings of the transformer. The inner and outer modular transformer bobbins are positioned such that the inner transformer bobbin is inserted into the outer transformer bobbin with the secondary windings surrounded by the primary windings. When assembled, the inner modular transformer bobbin has a protrusion that extends axially therefrom through the outer bobbin and terminates in first core retaining ears at one end of the transformer. Second core retaining ears extend from the opposite end of the transformer, and both ears receive the "E" shaped core halves, maintained in position on the transformer by bonding.
