This calculator will help you identify the value, tolerance and temperature coefficient of a color coded resistor by simply selecting the bands colors. It will also calculate the minimum and maximum values …

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.

Our printable resistor color code chart is regularly updated to ensure accuracy and includes all standard resistor types. Perfect for electronics enthusiasts, students, and professionals.

The Printable Resistor Color Code Chart matches the color bands on the resistor body to their digit, multiplier, and tolerance equivalents so you can decode values in seconds.

The resistor value is read from the left to right. If there is no tolerance band, then find the side that has a band closest to a lead and make that the first band.

The chart below shows how to determine the resistance and tolerance for resistors. The table can also be used to specify the color of the bands when the values are known.
