Standard Resistor Values and Color Coding
Resistors use colored bands to convey their resistance, tolerance, and, in some cases, wattage. While larger power resistors often carry printed numbers, miniature parts rely solely on color bands for identification.
| Color | Digit | Multiplier | Tolerance (%) |
| Black | 0 | 100 (1) | |
| Brown | 1 | 101 | 1 |
| Red | 2 | 102 | 2 |
| Orange | 3 | 103 | |
| Yellow | 4 | 104 | |
| Green | 5 | 105 | 0.5 |
| Blue | 6 | 106 | 0.25 |
| Violet | 7 | 107 | 0.1 |
| Grey | 8 | 108 | |
| White | 9 | 109 | |
| Gold | | 10-1 | 5 |
| Silver | | 10-2 | 10 |
| (None) | | | 20 |
In 5‑band resistors, the tolerance band is always present and uses brown, red, green, blue, or violet. A blank (20%) band appears only on 4‑band codes.
Color Code Examples
Yellow‑Violet‑Orange‑Gold
This resistor equals 47 kΩ with a ±5% tolerance.
Green‑Red‑Gold‑Silver
Value: 5.2 Ω, tolerance ±10%.
White‑Violet‑Black
Value: 97 Ω, tolerance ±20% (blank band indicates 20%).
Orange‑Orange‑Black‑Brown‑Violet
Value: 3.3 kΩ, tolerance ±0.1%.
Brown‑Green‑Grey‑Silver‑Red
Value: 1.58 Ω, tolerance ±2%.
Blue‑Brown‑Green‑Silver‑Blue
Value: 6.15 Ω, tolerance ±0.25%.
Preferred Values or E‑Series Standards
The IEC introduced E‑series in 1952 to standardize resistor values, easing mass production and ensuring component compatibility across manufacturers. These series span a logarithmic scale, providing a predictable set of values for every decade.
| E Series | Tolerance (SIG FIGS) | # of Values per Decade |
| E3 | 36%* | 3 |
| E6 | 20% | 6 |
| E12 | 10% | 12 |
| E24 | 5% | 24 |
| E48 | 2% | 48 |
| E96 | 1% | 96 |
| E192 | 0.5% – 0.25% and higher | 192 |
*The calculated tolerance for E3 is 36.60%; industry practice varies between 36–50%.

E96 and E192
These finer series offer tolerances of 0.5% or 0.25% but increase component count and cost. Use them only when circuit precision demands it.
