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 |
|---|---|
| 226J | 22 µF, ± 5 % |
| 226K | 22 µF, ± 10 % |
| 226M | 22 µF, ± 20 % |
| 226Z | 22 µF, +80 / −20 % |
| 2A226J | 22 µF, ± 5 %, rated 100 V |
| 1H226K | 22 µF, ± 10 %, rated 50 V |
Where you meet it
Microfarad values are used for decoupling and filtering supply rails. Ceramic chips of this size usually carry no marking; marked ones are mostly tantalum (band = positive) or film.

Frequently asked questions
What is a 226 capacitor?
A capacitor marked 226 is 22 µF: 22 followed by 6 zeros in picofarads, 22,000,000 pF, which is also 22,000 nF.
What is 226 in µF and nF?
226 = 22,000,000 pF = 22,000 nF = 22 µF.
What do 226J, 226K and 226M mean?
The same capacitance, 22 µF, with a tolerance of ± 5 % (J), ± 10 % (K) or ± 20 % (M).
