Is a 47uF 10v Capacitor higher than a 47uF 50v Capacitor

[2canSAM]

Getting ready to takle something and the directions call for a 47uF 10v Capacitor or higher. All I can find at ratshack is a 47uF 50V. Now knowing nothing is the 50v higher than the 10v?

I am not sure I know what you mean by is it "higher". I would assume that in most electrical designs, you should be able to substitute a higher voltage rated capacitor of the same technology without any problems (i.e. both are electrolytic or both ceramic capacitors). If it is a particularly high performance design or a switching power design, it *may* be an issue since the ESR values might be different. Otherwise, it would only likely be a difference in cost and size of the part, which is negligible for somebody who is not building in volume.

The 50V part will be fine. It will tolerate a higher voltage, but if your circuit doesn't need that, it won't hurt anything.

It's simply rated for a higher voltage. No functional problem, BUT it will be bigger. So if space is an issue, then you might not be able to use it.

What are you building? A Cmoy?

in that context, yes

the voltage rating of a capacitor is the MAXiMUM voltage that the capacitor can be used without damaging it

so if the circuit requires a 10v or HIGHER voltage capacitor, then a 50v capacitor will work just fine

Yep...

No, because the voltage capacity storage holder is 5 times larger, that means whatever circuit it's in, will short out 5 times faster.

C'est la vie.

The imporant question here is:

So what are you building?
