Will this capacitor work?

[iamtyler]

I couldnt find any 8 or so volt 100uf capacitors at radio shack while i was getting resistors for a TI regulator thats going in the portable im building. All the 100 uf capacitors they had there were 35+volts.
Now I pulled a 100uf capacitor off an old toy of my cousins... But its a ten volt capacitor. Could I use it on my regulator? Will there be negative/positive side effects of doing such?
All help really really appreciated

Actually, you're better off with the 35V ones.

It's a maximum voltage rating, not what voltage you're supposed to use. You could put 18V through a 35V capacitor, for example, but not through a 10V one (not a good idea anyway). You could use the 35V caps in a 1V circuit and it would be fine. As a general rule, use a capacitor rated for twice the voltage you'll be using it with. I'm assuming you're using this with 7.4V batteries, so a 16V capacitor will be about the minimum you should use. A 10V cap will probably work fine, but it's just bad practice to leave so little a margin.

Thanks for clearing that up =] I wasnt completely sure so I thought I'd play it safe before wiring it all up. Glad I did =)
thanks much XCVG =)
