Marking	Tolerance	Minimum	Maximum
`330J`	±5%	0.0000314 µF	0.0000347 µF
`330K`	±10%	0.0000297 µF	0.0000363 µF
`330M`	±20%	0.0000264 µF	0.0000396 µF

Other ways it's marked

On schematics and parts lists, the same capacitor appears as 33p, 0.033 nF or 0.000033 µF.

Where it's used

Values below 1 nF are typical in radio circuits, oscillators and high-frequency filters, usually as C0G (NP0) ceramic capacitors, which stay stable with temperature.

Frequently asked questions

What is the value of a 330 capacitor?

33 pF, the same as 0.033 nF or 0.000033 µF.

Is 330 the same as 33p?

Yes. 330 is the 3-digit code and 33p is the letter code for the same 33 pF.

What does the letter after 330 mean?

It's the tolerance: 330J is ±5%, 330K is ±10% and 330M is ±20%.

Does the code 330 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.
