Electronics Gurus - Capacitors

[f0xy]

I have a circuit, runs off 8v-12v...

It needs capacitors, 100uf, 1uf and 20nf (0.02uf).

Picking some up tomorrow from CPC, does it matter what voltage rating I get? I.e they stock 50v, 100v and higher....would a 100v do the job fine for example?

I always used 3x the maximum the circuit was intended to run as 'my' rule so either 50V or 100V would be ample.
