Free Resistor Color Codes Value Calculator (4, 5, 6-Band) Decoding resistor color bands is fast and flawless with our free online calculator. This tool automatically translates color bands into accurate resistance values, tolerance ranges, and temperature coefficients.
Using a Free Resistor Color Code Calculator removes the risk of manual reading errors, bad calculations, or mismatched components in your circuit designs. The Universal Resistor Color Code Chart
The standard system follows the international IEC 60062 standard. Each color represents a specific number, multiplier, or variance limit. Digit Value Multiplier Temperature Coefficient Black 250 ppm/°C Brown 100 ppm/°C Red 50 ppm/°C Orange 15 ppm/°C Yellow 25 ppm/°C Green 20 ppm/°C Blue 10 ppm/°C Violet 10,000,000 Gray White Gold Silver How to Determine the Value of 4, 5, and 6-Band Resistors
The main difference between these variations comes down to precision and environmental tracking. 4-Band Resistors (Standard Precision)
This is the most common variant found in general electronics.
