Features Potted Toroidal Transformers have the following advantages compared with traditional stacked lamination types: • Small size and low weight • Extremely low level of radiated magnetic field • Double insulated primary leads • Warming is kept to a minimum with short wire lengths in the windings and heat-conductive potting. • Very low iron loss • Easy to mount due to mounting hole in polyamide housing • Protection against mechanical damages • Very low induced noise (hum) • Not suitable for audio devices
