Capacitor

Using Arduino General Electronics

Hi All,
I've got a little (752mmm) whitish rectangular capacitor probably made of some type of plastic.
It's marked with "J" on the backside .. obviously referring to tolerance. The frontside is marked like this:

.1
63

and my guess is, that it is a 630 nF capacitor. But it's a guess. Is there any way to assertain that I can use it in a 5V setup as a 630 nF capacitor (except for trying)?

Another of same type, but colored blue has two odd symbols: an S with a slash across, and one that almost looks like en n:

s6n8J63 ..

[edit] I've noticed a third with 63 referring to voltage .. that's beginning to make sense

The .1 tells me it's probably more likely a 100nF. You often see them between DIP chips on older boards for decoupling.

Otherwise, it's a 63pF, which to my thinking is an odd number. 100nF is far more likely.

The J is the accuracy, or tolerance - in this case +/- 5%

I agree. Guess is that this is a 0.1uF (100nF) 63Volt capacitor. So don't go applying >63 volts to it.
