For example, how do you protect a TQ2-5V relay from current overload? The nominal current is small at about 28.1 mA. If it's a 5V relay. I can limit the Vcc to 5 V that's no problem. But if I wanted to put a fuse in the circuit to limit the current through the coil how could I do that. Are there any fuses that can work at that level?
