    hi all
    i have made this circuit today only problem is it says use a 47uf 6.3 v but i do not have any 6.3v but i have 10v and 16v 47uf will ether of them substitute the 6.3v withoud damage to the rest of the circuit


    thanks

    Yes. For polarized capacitors, you can use a higher voltage rating than specified. I wouldn't go so far as to use a 500V polarized cap in a 9V circuit.

    The "rule of thumb" for capacitors is to use twice the rated voltage as you may see across the capacitor in the circuit. Since the output of the regulator is 5v, you should use a cap rated for 10v.
