In this system the first two or three digits indicate the numerical resistance value of the resistor and the last digit gives a multiplier.
The number of the last digit indicates the power of ten by which to multiply the given resistor value. Here are some examples of values under this system:
1 . 450 = 45Ω x 100 is 45Ω
2. 273 = 27Ω x 103 is 27,000Ω (27kΩ)
3. 7992 = 799Ω x 102 is 79,900Ω (79.9kΩ)
4. 1733 = 173Ω x 103 is 173,000Ω (173kΩ)
The letter “R” is used to indicate the position of a decimal point for resistance values lower than 10 ohms. Thus, 0R5 would be 0.5Ω and 0R01 would be 0.01Ω.
