Resistor colour code

Resistor values are often indicated with colour codes. Practically all leaded resistors with a power rating up to one watt are marked with coloured bands. The coding is defined in the international standard IEC 60062: this standard describes the marking codes for resistors and capacitors. The colour code is given by several bands. The number of bands varies from three to six. As a minimum, two bands indicate the resistance value and one band serves as multiplier.
This tool is used to decode information for colour banded axial lead resistors. Select the number of bands and the colours to determine the value of the resistors. Touch and hold the result label to restore.
