The construction of the E6.3 push-pull transformer is made using a two section bobbin. The primary and secondary windings are made of copper wire and a plastic cap enables a smooth pick and place process. The series offers different turns ratios in a very compact size. The components are RoHS compatible and are intended to be used at a typical switching frequency of 250kHz. Typical applications for these push-pull transformers are, but are not limited to, switch-mode power supplies, isolated interface power supplies, industrial automation, and process control.
