You don't say what the capacitance of the original capacitor is. Being a capacitor following a bridge rectifier it will be a smoothing, or more correctly a reservoir, capacitor with a high capacitance value.

The great thing about electrolytic capacitors is that you get a lot of capacitance in a small package. I have some 1uF polypropylene types here and they are huge.
