Resistor color code: The resistor color code calculator

The resistor color code calculator makes it easy to identify and select resistance and tolerance values for 4, 5, and 6 band through hole resistors . Learn how to use the resistor color code to identify the resistance and tolerance of 3, 4, 5, and 6 band axial resistors. This resistor color code calculator lets you find any resistor value by simply choosing the color of each band. Or check out the table. The resistor color code is a standardized system used to indicate the resistance value, tolerance, and sometimes the temperature coefficient of a resistor. By examining the color bands on a resistor, one can determine its resistance value according to the color code chart.
