Resistor Color Code Calculator
Through-hole mounted resistors, one of the most used types of electronic components, come in many shapes and flavors. Some types may have resistance values printed on them, but most are color coded to indicate resistance values and ratings.
The color code consists of several colored bands which indicate the resistance values of resistors in Ohms as well as the tolerance rating. Most resistors have four or five bands, but occasionally you may come across resistors with three or six bands.
There is also as special case, a resistor with one black band. This is a zero-ohm resistor, i.e. not really a resistor but rather a piece of wire.
The most common types of resistor codings are explained here.
The calculator
Please select the color for each band in the drop-down lists and press the Calculate button. The resistance and ratings will be calculated and shown.
