Capacitor manufacturers generally give the value of capacitor on capacitor but, in some cases there may be not enough space. In that case, they use simple notation. If it is 2 digits number then no issues. You can say the value seen is the value on capacitor. But if it has 3 digits then the first two digit you take as is and remaining last digit is the number of zeros following that first two digits. See table below;
| DIGITS | CAPACITANCE (pF) |
| 101 | 100 |
| 221 | 220 |
| 471 | 470 |
| 102 | 1000 |
| 222 | 2200 |
| 472 | 4700 |
| 103 | 10000 |
| 223 | 22000 |
| 473 | 47000 |
| 104 | 100000 |
| 224 | 220000 |
| 474 | 470000 |
| 105 | 1000000 |
| 225 | 2200000 |
Another notation on capacitor is tolerance. See table below;
| Letter | Tolerance |
| A | ±0.05 pF |
| B | ±0.1 pF |
| C | ±0.25 pF |
| D | ±0.5 pF |
| E | ±0.5% |
| F | ±1% |
| G | ±2% |
| H | ±3% |
| J | ±5% |
| K | ±10% |
| L | ±15% |
| M | ±20% |
| N | ±30 |
| P | -0% +100% |
| S | -20% +50% |
| W | -0% +200% |
| X | -20% +40% |
| Z | -20% +80% |
