Shop for your transistor components for your hobby electronics. Transistors are simple electrical components that are designed to boost the signal and act as an amplifier. One example of a transistor is a MOSFET. MOSFET transistors are generally used in conjunction with raw sensor components to amplify the signals they receive which can then be used by your micro controller of choice such as the Raspberry Pi or Arduino. We don’t stock a large range of transistors as for the average hobby electronics project you will be unlikely to need them, but please do get in touch if you are looking for something specific as it is highly likely that we will be able to source this from our supply chain.
