Resistor Color Code

🎨 Band 1 Color Selection1st Digit

Select the color matching this band on your physical resistor to calculate:

4.7 kΩ

Tolerance: ±5%

Math:(4 × 10 + 7) × 100 Ω=4.7 kΩ

Standard preferred values allow you to select standard resistors that are commercial stock models.

E12 Match

4.7 kΩ

E24 Match

4.7 kΩ

E96 Match

4.75 kΩ

Resistor color code calculator with E-series matching

This tool works both ways: decode physical resistor bands or enter a target value to generate the nearest resistor color bands.

Switch between 4-band, 5-band, and 6-band resistors to include tolerance and temperature coefficient when your part needs tighter specifications.

Use the E12, E24, and E96 matches to choose a commercially available resistor instead of designing around a value that is hard to source.
