Decode resistor color bands to ohms — or find the bands for any resistance value.
4.7 kΩ ±5%
Minimum (-5%)
4.465 kΩ
Maximum (+5%)
4.935 kΩ
Band 1 — 1st digit — Yellow (4)
Band 2 — 2nd digit — Violet (7)
Band 3 — multiplier — Red (×10²)
Band 4 — tolerance — Gold (±5%)
Standard IEC 60062 color code: 4-band (2 digits + multiplier + tolerance), 5-band (3 digits), 6-band adds a temperature coefficient. Everything runs entirely in your browser.
Decode 4-band, 5-band and 6-band resistor color codes into resistance values with tolerance ranges and temperature coefficients, or work in reverse: enter a resistance and get the matching color bands. Features clickable color swatches and a live SVG resistor drawing that updates as you pick colors. Runs entirely in your browser.
