I'm using a micro relay to switch some stuff. The design is a constant 12v+ and uses a transistor to switch the 12v-. I want to put a delay in it with a capacitor. But where would you put that? Between the coil neg and ground?
You can put it directly from the relay + terminal to ground. You can use a much smaller value capacitor however if you put it on the base of the switching capacitor to ground as it draws MUCH less current than the relay itself.
