Instantly decode resistor values with our comprehensive Resistor Color Code Calculator. Whether you're working with 4-band, 5-band, or 6-band resistors, accurately find resistance in ohms, tolerance, and temperature coefficient for your electronics projects. Simplify component identification and ensure precision in your circuits.
Formula:
The resistor's value is derived from its colored bands. Typically:
- Band 1: First significant digit
- Band 2: Second significant digit
- Band 3 (for 5/6 band): Third significant digit
- Multiplier Band: Power of 10 to multiply by
- Tolerance Band: Permissible variation from nominal value (%)
- Temperature Coefficient Band (for 6 band): PPM/°C change in resistance
Value = (Digit1 Digit2 Digit3) × Multiplier ± Tolerance
