Input capacitor? Do you mean for EMI filtering on the input or do you mean the input capacitor to the rest of the circuit which will be the boost capacitor of the PFC block. The boost capacitor should be of a type that can handle high ripple current, so something with a low ESR value to reduce heating in this cap.
