capacitor ID help!

hi guys, i'm not entirely sure wether to post this under chip amps or here in electronics, but what i'm wondering primarily definitely belongs here.
i have some little yellow mkt ( i think) caps i've salvaged, with the code 100nJ63 printed on top. i understand the 100n to mean .1uf and the j to mean 5% tolerance, but i haven't been able to track down of the meaning of the 63.
i'd like to use them to bypass the power rail caps in a gainclone project, but i'm unclear on wether they need to be rated for voltage the same way as the 1000uf electrolytics they would be in parallel with are, and if so how do i go about finding out their voltage rating.

thanks,
ryan

Hi Ryan.
This may be useful to you.

It was a little too big (5 pages) to post to the forum.
Cheers

Greetings from another part of Australia. In this context "63" is almost certainly the voltage rating. Cheers

thanks for the quick reply! according to that very informative page, the capacitor in question would be .1uf 5% 63v. thanks again
