Decode resistor color bands into resistance and tolerance values
Select the resistor band colors and this tool will calculate the approximate resistance value, multiplier, and tolerance for common 4-band and 5-band resistor formats.
Band Selection
Switch between 4-band and 5-band decoding and choose the matching resistor colors.
Color-code output is recalculated whenever you change a band.
