Resistance to Color Code Calculator

This calculator performs the reverse lookup for axial resistors. By entering a target resistance value, it identifies the nearest standard manufacturing value and displays the correct color band sequence for your circuit.

Use this tool to:

  • Find the closest standard E24/E96 value to your theoretical calculation to ensure your design uses commercially available components.
  • Visualize the color bands before heading to the workbench, making it easier to pull the correct parts from storage.
  • Determine the difference between 4-band and 5-band versions of the same resistance value to suit your precision requirements.
