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 |
|---|---|
| 334J | 330 nF, ± 5 % |
| 334K | 330 nF, ± 10 % |
| 334M | 330 nF, ± 20 % |

Where you meet it
Nanofarad values are used in filters, snubbers, timing and coupling, as ceramic (X7R, C0G) or film capacitors.

Frequently asked questions
What is a 334 capacitor?
A capacitor marked 334 is 330 nF: 33 followed by 4 zeros in picofarads, 330,000 pF, which is also 0.33 µF.
What is 334 in µF and nF?
334 = 330,000 pF = 330 nF = 0.33 µF.
What do 334J, 334K and 334M mean?
The same capacitance, 330 nF, with a tolerance of ± 5 % (J), ± 10 % (K) or ± 20 % (M).
