5 Band Resistor Color Code Tool: This tool is used to calculate the information for color banded axial lead resistors of 5 band. Select the number of bands, then their colors to determine the value and tolerance of the resistors.
The number of bands is important because the decoding changes based upon the number of color bands. For the 5 band resistor:
Band 1 – First significant digit
Band 2 – Second significant digit
Band 3 – Third significant digit
Band 4 – Multiplier
Band 5 – Tolerance
Resistance = (First Significant Digit . Second Significant Digit. Third Significant Digit) * Multiplier ± Tolerance %
