Can you use a different voltage capacitor? Member.

Can a higher rated capacitor store more voltage?

No, having a higher rated cap will not somehow store up more voltage than is available in the circuit. You actually want a cap with a slightly higher voltage rating than the highest voltage you expect to put across it. Can you replace capacitor with lower voltage?

Will a higher voltage capacitor work at a lower voltage?

The voltage rating of a capacitor is the maximum only, they will work fine at any voltage less than or equal to this. Higher voltage capacitors have a lower ESR anyway, so you could improve the performance that way. Can I replace capacitor with lower UF and higher voltage?

Can you replace a capacitor with a higher UF?

You will need to match up the uF, although most capacitors have a 10 to 20% tolerance.
