About This Resistor Color Code Calculator
This browser-based resistor color code calculator helps you quickly determine the resistance value, tolerance, and temperature coefficient of through-hole resistors based on their color bands. The electronic color code is an international standard defined in IEC 60062 used to indicate the values of electronic components. All calculations happen in your browser - your data remains private.
Key Features:
- Multiple Band Support: Calculate values for 3-band, 4-band, 5-band, and 6-band resistors
- Complete Information: Shows resistance value, tolerance percentage, and temperature coefficient (TCR) for precision resistors
- Visual Color Selection: Interactive color band selector with actual resistor colors for easy identification
- Standard Compliant: Based on IEC 60062 international standard for electronic color codes
🔒 Privacy-Friendly: All calculations are performed entirely in your browser. No data is sent to any server.
⚠️ Disclaimer: This calculator is provided for educational and reference purposes only. Always verify resistor values with a multimeter before use in critical applications. Color perception may vary, and resistor markings can fade or be difficult to read.
