Resistor Colour Code Calculator
This calculator converts resistor values to or from
5-band or 4-band colour codes.
To convert from value to colours:
Select the resistor type (4 or 5 bands) using the radio buttons. Type the resistance in the box below and select the
units and (optionally) the tolerance
from the drop-down boxes. The colour bands will be displayed below on the image of the resistor.
To convert from colours to value:
Select the resistor type (4 or 5 bands) using the radio buttons. Hover the mouse over the coloured bands on the image of the resistor to
display the colour selector box, then click on the required
colour. Repeat for all bands (tolerance is optional). The resistance will be shown in the box above the image, along with the units
and tolerance.
Preferred resistor values:
Converting a value either way will display the nearest preferred resistor value below the image of the resistor. Use the radio buttons
below the image to select the series of preferred values to use (E12 - E192).
