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 |
|---|---|
| 105J | 1 µF, ± 5 % |
| 105K | 1 µF, ± 10 % |
| 105M | 1 µF, ± 20 % |
| 105Z | 1 µF, +80 / −20 % |
| 2A105J | 1 µF, ± 5 %, rated 100 V |
| 1H105K | 1 µF, ± 10 %, rated 50 V |
Where you meet it
Values like this sit at the input and output of voltage regulators and as bulk decoupling on a supply rail. In this range most are ceramic chips, which carry no marking; a printed code usually means a tantalum or film capacitor.

Frequently asked questions
What is a 105 capacitor?
A capacitor marked 105 is 1 µF: 10 followed by 5 zeros in picofarads, 1,000,000 pF, which is also 1,000 nF.
What is 105 in µF and nF?
105 = 1,000,000 pF = 1,000 nF = 1 µF.
What do 105J, 105K and 105M mean?
The same capacitance, 1 µF, with a tolerance of ± 5 % (J), ± 10 % (K) or ± 20 % (M).
