I have a missing resistor that I need to replace but i need and i.d.
Can anyone tell me what the 20 is and am I able to use something similar coz i dont have exact same one on donor board?
20 means it’s a 20 ohm resistor. It’s a 20ohm resistor 1/16 Watr MF-LF 402 piece. That’s what you would enter in Mouser or Digikey if you buy it individually. Otherwise you can steal a resistor from a different board with the same values.
