The voltage rating on a capacitor is the voltage level above which it is likely to explode and get very messy. The voltage doesn''t affect the capacitance in any way. As long as you stay well below the rated current all will be fine. The closer you get to that rated current, the more likely you are to run into manufacturing tolerances and ...
