Resistor Color Code Calculator

All tools

Decode 4, 5 and 6-band resistors. Pick the band colors and instantly read the resistance, tolerance and temperature coefficient with a live resistor preview.

Resistance –
Minimum value –
Maximum value –
Temperature coefficient –
Digit bands give the significant figures, the multiplier scales them, and the tolerance band sets the allowed range. The 6th band (when present) gives the temperature coefficient in ppm/°C.
