Low-Profile Encapsulated Transformers

Low-Profile Encapsulated Transformer Features
The OB Range is mounted in resin-filled, flat thermoplastic cases and designed to be through-hole soldered direct to PCB's. Four screws using holes molded in the corners of the case can supplement mechanical fixing.

The non-concentric twin primary and secondary windings are wound on separate bobbins, which gives maximum isolation and low inter-winding capacitance.

The flat height profile allows for close spacing between boards.
