225 capacitor value

The code 225 reads as 22 × 10⁵ pF: 2,200,000 pF, which is the same as 2,200 nF or 2.2 µF.

With a tolerance letter

Marking	Tolerance	Minimum	Maximum
`225J`	±5%	2.09 µF	2.31 µF
`225K`	±10%	1.98 µF	2.42 µF
`225M`	±20%	1.76 µF	2.64 µF

Other ways it's marked

On schematics and parts lists, the same capacitor appears as 2u2, 2,200 nF or 2.2 µF.

Where it's used

From 1 µF up, they filter power supplies, set timings and couple audio. Multilayer ceramic capacitors reach these values in small sizes; above about 10 µF, electrolytics are more common.

Frequently asked questions

What is the value of a 225 capacitor?

2,200,000 pF, the same as 2,200 nF or 2.2 µF.

Is 225 the same as 2u2?

Yes. 225 is the 3-digit code and 2u2 is the letter code for the same 2.2 µF.

What does the letter after 225 mean?

It's the tolerance: 225J is ±5%, 225K is ±10% and 225M is ±20%.

Does the code 225 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.
