What is included

The file contains the color name, common two-letter code, significant digit where applicable, multiplier, tolerance, and temperature coefficient. Blank cells mean that the color is not normally used for that particular role.

How to use the file

  1. Open the CSV in a spreadsheet or text editor.
  2. Use the digit columns for the significant figures and the multiplier column for the power-of-ten step.
  3. Use the tolerance and temperature coefficient columns as reference fields, then verify the part marking and datasheet.
