Electronic transformers are some of the most critical electronic components found in electrical circuits. Transformers are vital because they alter the voltage from input to output – literally, transforming the electrical voltage to suit the particular application it is feeding. Usually this means reducing it significantly – mains electricity arrives in homes at around 240 volts, enough to fry most domestic circuits. Choose from an extensive range of audio transformers, chassis transformers, encapsulated transformers, ferrite transformers, lighting transformers, PCB transformers, power transformers, pulse transformers and toroidal transformers.
