With a tolerance letter

Marking	Tolerance	Minimum	Maximum
`685J`	±5%	6.46 µF	7.14 µF
`685K`	±10%	6.12 µF	7.48 µF
`685M`	±20%	5.44 µF	8.16 µF

Other ways it's marked

On schematics and parts lists, the same capacitor appears as 6u8, 6,800 nF or 6.8 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 685 capacitor?

6,800,000 pF, the same as 6,800 nF or 6.8 µF.

Is 685 the same as 6u8?

Yes. 685 is the 3-digit code and 6u8 is the letter code for the same 6.8 µF.

What does the letter after 685 mean?

It's the tolerance: 685J is ±5%, 685K is ±10% and 685M is ±20%.

Does the code 685 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.
