470 ohm Resistor color code- 470R bands
The 470 ohm Resistor color code for 4-band is as shown in the image below:
[Yellow, Violet, Brown, Gold]
| Band | Color | Value | ||
|---|---|---|---|---|
| 1st yellow |  | 4 | ||
| 2nd violet |  | 7 | ||
| 3rd brown |  | 10 | ||
| 4th gold |  | 5% | ||
| 470±5% Ω |
470 ohm resistor color code for 4-band is calculated as:
- (1st digit) = Yellow = 4
- (2nd digit) = Violet = 7
- (multiplier) = Brown = 1 = 10^1 = 10
- (tolerance) = Gold= ±5%
∴ 47×10±5% –> 470 ohms –> 470 Ω
∴ the real value of 470 Ω resistor is between 446.5 Ω to 493.5 Ω
Description: From the resistor code chart we found the color code of resistor with respect to the decimal value of the respective band counted from left to right.
So for 470-ohm resistor, 1st digit is ‘ 4 ‘, ∴ look for color in a chart with value 4, then it’s your 1st color(say yellow). The next 2nd digit is ‘ 7 ‘, ∴ look for color in a chart with value 7, then it’s your 2nd color (say violet). Next 3rd digit ‘0’ (but value 10^1 = 10) is multiplier ‘ 1 ‘, ∴ look for color in a chart with value 1, then it’s your 3rd color band (say brown).
- The last bands in 4 or 5-bands resistors are the indicator of the tolerance value of the resistor. Here, it is Gold indicates a 5% tolerance value. For Silver, its values is 10%, and Brown indicates 1% tolerance. If the 4th band is absent it is considered in 20% tolerance value.
