Calculator 22 / IEC 60062

Resistor color code

Type in the resistance value you want and read back the IEC 60062 color bands — including how many of each color you need and the resulting tolerance range. Works in 4-band and 5-band.

4-band marking read left to right: 47 × ×100 = 4700 Ω ±5%.

IEC 60062 (EIA RS-194)

Nominal value

4700 Ω ±5%

Bands encode 47 × ×100 = 4700 Ω, tolerance band Gold = ±5%.

IEC 60062 (EIA RS-194)

Tolerance range

4465 Ω – 4935 Ω

4700 Ω × (1 − 0.05) = 4465 Ω · × (1 + 0.05) = 4935 Ω.

Amount of each color

Yellow ×1 · Violet ×1 · Red ×1 · Gold ×1

4 bands total (2 digit + 1 multiplier + 1 tolerance).

How this was calculated

  1. Parse the input 4700 to ohms: 4700 Ω.
  2. Normalize to 2 significant digits: 4700 Ω → 47 × ×100.
  3. Digit bands: Yellow = 4 · Violet = 7.
  4. Multiplier band: ×100 → Red.
  5. Tolerance band: ±5% → Gold; range = 4700 Ω × (1 ∓ 0.05) = 4465 Ω – 4935 Ω.

Color-code reference

IEC 60062 (formerly EIA RS-194) — read digit bands from left, then the multiplier, then the tolerance band (wider gap).
