Other ways it's marked

On schematics and parts lists, the same capacitor appears as 33n, 33 nF or 0.033 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 333 capacitor?

33,000 pF, the same as 33 nF or 0.033 µF.

Is 333 the same as 33n?

Yes. 333 is the 3-digit code and 33n is the letter code for the same 33 nF.

What does the letter after 333 mean?

It's the tolerance: 333J is ±5%, 333K is ±10% and 333M is ±20%.

Does the code 333 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.
