With a letter or a voltage code
The letter after the code is the tolerance, and a digit-letter pair in front of it is the rated voltage on film capacitors and some ceramics:
| Marking | Meaning |
|---|---|
| 102J | 1 nF, ± 5 % |
| 102K | 1 nF, ± 10 % |
| 102M | 1 nF, ± 20 % |
| 102Z | 1 nF, +80 / −20 % |

Frequently asked questions
What is a 102 capacitor?
A capacitor marked 102 is 1 nF: 10 followed by 2 zeros in picofarads, 1,000 pF, which is also 0.001 µF.
What is 102 in µF and nF?
102 = 1,000 pF = 1 nF = 0.001 µF.
What do 102J, 102K and 102M mean?
The same capacitance, 1 nF, with a tolerance of ± 5 % (J), ± 10 % (K) or ± 20 % (M).
