Since this is the EIA coding system, the value will be in picofarads. Hence, the value of the capacitor above is 47000 pF $\pm$5 %. A ceramic disc capacitor does not have a polarity and connects in any direction on the printed circuit board. If you are new to capacitor codes, then the best way to start is with a chart, because that way, you can see the arrangement of the code. Engineers usually do not require calculators because the code is so simple. Here is another example, code 104 is 10 followed by four zeros, hence 10 0000 pF.
| 1st Digit | 2nd Digit | 3rd Digit (Multiplier ) | Tolerance Letter | ||
| 0 | 0 | 0 | 1 | C | 0.25 pF |
| 1 | 1 | 1 | 10 | D | 0.5 pF |
| 2 | 2 | 2 | 100 | E | 1 pF |
| 3 | 3 | 3 | 1000 | G | 2 % |
| 4 | 4 | 4 | 10000 | J | 5 % |
| 5 | 5 | 5 | 100000 | K | 10 % |
| 6 | 6 | 6 | 1000000 | L | 15 % |
| 7 | 7 | 7 | 10000000 | M | 20 % |
| 8 | 8 | 8 | 100000000 | N | 30 % |
| 9 | 9 | 9 | 1000000000 | Z | +80 % to 20 % |
Example:
If a capacitor is marked 103J, its value is 10,000 pF 5 %. If a capacitor is marked 335K, its value is 3300000 pF 10 %
