    I have a super small relay out of a HP printer, the coil reads 35 ohms I was just curious what the approximate voltage for the coil may be? also is there a website that is a good place to look up part numbers and specks?

    The coil's resistance doesn't tell you much about the operating voltage. Since the relay is from a printer, the rating may well be 3.3V or 5V.

    Enter the pat number (should be printed somewhere on the relay's housing) into Google or tell us.
