Resistor Color Code
Decode 4, 5, and 6-band axial resistor color codes into resistance, tolerance, and temperature coefficient.
Adjust inputs and the results update automatically.
Band Configuration
How it works
R = (digits) × multiplier ± tolerance%
Each band encodes either a significant digit, a power-of-ten multiplier, a tolerance, or (6-band only) a temperature coefficient in ppm/°C.
