With a tolerance letter

Marking	Tolerance	Minimum	Maximum
`103J`	±5%	0.0095 µF	0.0105 µF
`103K`	±10%	0.009 µF	0.011 µF
`103M`	±20%	0.008 µF	0.012 µF

Other ways it's marked

On schematics and parts lists, the same capacitor appears as 10n, 10 nF or 0.01 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 103 capacitor?

10,000 pF, the same as 10 nF or 0.01 µF.

Is 103 the same as 10n?

Yes. 103 is the 3-digit code and 10n is the letter code for the same 10 nF.

What does the letter after 103 mean?

It's the tolerance: 103J is ±5%, 103K is ±10% and 103M is ±20%.

Does the code 103 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.
