Resistor Color Code

Metal film resistors with less tolernace than carbon film ressitors are marked with five colored rings giving the value and the tolerance. The coding scheme is similar to that of resistors with four rings though an additional digit is shown for the mantissa.

	mantissa					exponent			tolerance
