Decode a capacitor
Enter the printed code (e.g. 104): the tool shows the capacitance in pF, nF and µF.
Common codes
| Code | pF | nF | µF |
|---|---|---|---|
| 101 | 100 | 0.1 | 0.0001 |
| 104 | 100,000 | 100 | 0.1 |
| 224 | 220,000 | 220 | 0.22 |
| 475 | 4,700,000 | 4,700 | 4.7 |

Frequently asked questions
How to read the code?
The first 2 digits are the value, the 3rd the number of zeros, in pF. 104 = 10 followed by 4 zeros = 100,000 pF.
What does “R” mean?
It marks the decimal point: 4R7 = 4.7 pF, R47 = 0.47 pF.
And the tolerance letter?
A trailing letter (J = ±5%, K = ±10%, M = ±20%) gives the tolerance; it does not change the nominal value.
