Read any resistor in seconds

Click the color bands to match your physical resistor and instantly get the resistance value, tolerance, and (for 6-band parts) temperature coefficient. Supports 4-band, 5-band, and 6-band resistors using the standard IEC 60062 color code — a must-have reference for electronics students and hobbyists.
