Are there any other considerations I need to follow when choosing a .56 Ohm (560 mOhm) 2W wirewound resistor replacement for one that is open? There are no color bands on the resistor. It does have .56 Ohm, 481, and 2WJ imprinted on it. I am guessing the 2WJ is the wattage and the .56 Ohm is obviously the resistance. Does the 481 mean anything? Thanks in advance for your reply.
