Decode 4-, 5- or 6-band resistor colors into resistance, tolerance and temperature coefficient with both text and color.
Your input
Outputs are cleared when the input changes.
Result
Enter your data or use the example, then run the tool.
Worked example
4-band brown, black, red, gold gives 1,000 Ω ±5%.
5-band brown, black, black, red, brown gives 10,000 Ω ±1%. Gold cannot be a digit band.
Method
Read significant digits, multiply by the color’s factor and apply the tolerance percentage. A sixth band supplies temperature coefficient.
The diagram uses the selected order and labels every color in text; no camera or direction inference is performed.
Limits
Only supported color/role combinations are accepted. A leading black digit, pink multiplier, single black zero-ohm jumper and non-resistor components are not decoded.
Choose the reading direction yourself. This does not identify a component, certify its rating or provide energized-circuit instructions.
