Can the capacitor be used if its capacity is reduced
Tantalum capacitors are commonly used for medium range levels of capacitance. They are best used when the size and performance matters, but they do not usually have high working voltages and don''t have very high current capacity. Tantalum capacitors are polarized and can explode when placed under stress.

capacitor
When the load is so heavy that the ripple is too large, you can use a bigger capacitor, because that smooths the line more. Therefore, it depends on the load what value you need for a capacitor. ... With lower ripple, you can reduce the input voltage (while maintaining the minimum) and thereby reducing the dissipation in the regulator ...

Power factor improvements
Low power is not only inefficient, but can also be expensive over the life of an electrical system. Many utility companies charge their industrial customers an additional demand fee if their power factor is less than a predetermined power factor value. In addition to the energy cost, there is a loss of the electrical system''s overall capacity.

If practical capacitors were purely capacitive, then indeed, a larger capacitor would do an even better (or at least "as good") job of filtering high frequencies as a smaller value one.. But capacitors are not purely capacitive; ones we can practically build are also unfortunately inductive, and at some frequency the inductive behavior dominates …
