In this electronics basics episode, we will be having a closer look at overvoltage/surge protection components. Now a voltage surge only occurs rarely through lightning, inductive switching in your grid or an electrostatic discharge. But if they hit your electronics, they can immediately destroy them. But with the 3 shown components you can easily and for pretty cheap save your circuits. Let's get started!
