In summary, the construction of the EPCOS E6.3 push-pull transformer consists of a two section bobbin. The primary and secondary windings are made of copper wire and a plastic exterior cap allows them to be used in a pick-and-place process. The series is designed to be used at a typical switching frequency of 250kHz and offers different turns ratios to define the output voltages. The components are RoHS compatible and include switch-mode power supplies, isolated interface power supplies, industrial automation, process control, and more.
