WebSMD Resistor Code Calculator. The surface mount resistor code calculator can be used to determine the resistance value of an SMD resistor using the markings found on the … WebTypical sizes for small resistors are 1/8 Watt, 1/4 Watt, 1/2 Watt, 1 Watt, and so on. So in our case a 1/4 Watt (0.25) might be on the small size, but a 1/2 (0.5) Watt resistor should be …
