That Is a very difficult question to answer without more information. Especially since we are talking .01 amps which is 10ma - that is a very small amount of current.
First, what is supplying the power? If it's just a small battery that can't supply much current you mught not need a fuse.
A fuse protects a circuit from drawing too much power if there is a problem, and usually you rate a fuse for about 25% more power than you expect to need. However at 10ma, that would be 15ma and I don't think you can get fuses that small. I would get the smallest fuse you can- that will probably be about 1 amp. Unfortunatley with such a small current requirement, your circuit will probably go up in smoke before the fuse blows.
So for such a small circuit, I wouldn't use a fuse. If you absolutley need one (for safety) just use the smallest fuse you can get.
