Other ways it's marked

On schematics and parts lists, the same capacitor appears as 2n2, 2.2 nF or 0.0022 µF.

Where it's used

Values from 1 nF to 1 µF are used for filtering, timing and signal coupling. Ceramic X7R capacitors and film capacitors are the usual choice.

Frequently asked questions

What is the value of a 222 capacitor?

2,200 pF, the same as 2.2 nF or 0.0022 µF.

Is 222 the same as 2n2?

Yes. 222 is the 3-digit code and 2n2 is the letter code for the same 2.2 nF.

What does the letter after 222 mean?

It's the tolerance: 222J is ±5%, 222K is ±10% and 222M is ±20%.

Does the code 222 show the voltage?

No. The voltage is printed separately (such as 50V, or a code like 2A, which means 100 V) or only given in the datasheet. Replace it with a capacitor rated for the same voltage or higher.
