Resistor Colour Code

Decode or encode 4, 5 and 6-band resistor colours, and find the nearest E6–E96 standard value.

● Runs on your device; nothing is uploaded

How to use it

  1. Choose 4 bands, 5 bands or 6 bands.
  2. Under Colours → value, pick each band colour to read value, tolerance and range.
  3. Under Value → colours, type a Resistance such as 4700, 4.7k or 4k7.
  4. Click Show on the resistor to copy those bands onto the drawing.
  5. Check the Nearest standard values table for E6 to E96.

Limits

Significant digits when encoding
2 (4-band) or 3 (5- and 6-band)
Multiplier
×0.01 to ×1 G
Smallest encodable value
0.1 Ω (4-band), 1 Ω (5- and 6-band)
Features
  • Colours follow IEC 60062
  • Temperature coefficient from the sixth band in ppm/K
  • Accepts RKM notation such as 4k7, 2M2 and 0R22
  • Nearest E6, E12, E24, E48 and E96 values with the error in %
