Our Resistor Color Code Calculator is a must-have for anyone working with electronics! Whether you’re an engineer, student, or hobbyist, this tool instantly decodes 4, 5, or 6-band resistors, giving you accurate ohm values, tolerance, and temperature coefficients—no manual calculations needed.

1. Select Bands: Choose between 4, 5, or 6 bands.

2. Pick Colors: Click each band to set its color (e.g., Brown for “1,” Red for “2”).

3. Calculate: Hit the button to see the resistor’s value, tolerance, and more!

✔ Smart Auto-Calculation: Results update dynamically as you select colors.
✔ Multi-Band Support: Handles 4-band (common), 5-band (precision), and 6-band (temp-sensitive) resistors.
✔ Unit Conversion: Displays resistance in Ω, kΩ, or MΩ for easy reading.
✔ Temperature Coefficient: For 6-band resistors, shows stability under heat (e.g., 100ppm/°C).

• Tab: Jump between band selectors.

• Arrow Keys: Cycle through color options.

• Enter: Calculate instantly.

Works flawlessly on any device—desktop, tablet, or phone. The clean layout adjusts automatically, so you can decode resistors on the workbench or on the go!
