What is a 6-Band Resistor?
A 6-band resistor is a type of precision resistor with six color bands that indicate its resistance value, tolerance, and temperature coefficient. These resistors are commonly used in high-accuracy circuits, where precise resistance is crucial.

Formula of 6 Band Resistor Color Code Calculator
R = (D1D2D3) × 10M
where:
- D1, D2, D3 = First three significant digits
- M = Multiplier
Example Calculation
Let’s assume we have a resistor with the following bands:
- Brown (1) | Black (0) | Red (2) | Orange (10³) | Gold (±5%) | Blue (10 ppm/°C)
R =(102) × 103 = 102,000 Ω or 102kΩ
- Tolerance = ±5% (Gold)
- Temperature Coefficient = 10 ppm/°C (Blue)
Thus, the resistance can vary between 96.9kΩ and 107.1kΩ depending on tolerance.
