Toroidal transformers provide a higher output compared to traditional E-I transformers of a similar physical size. They have substantially reduced radiated hum and electrical noise, generate less heat and have much better regulation making them ideal for high performance, low noise circuits.

The transformer is “potted” in an epoxy compound within a plastic housing. Configured with 2 x 120V primaries and 2 identical secondaries which can be wired in either series or parallel. Being PCB mount reduces assembly time as the transformer simply solders to the PCB. For extra stability and mechanical reliability the transformer can be secured to the PCB with a self tapping screw.
