    What capacitor?
    Do you mean all capacitors in general?
    Here is a 5000F capacitor in the Digi-Key catalog.

    Most capacitors don't need to be anywhere near 1 farad to do their job.

    Why is the unit so large? Because it's defined as a capacity that produces 1V per stored amp-second. Those are all reasonable units, but it's more capacity than you usually need.

    1F capacitors are common enough, marketed at car-audiophools at really silly prices.

    Supercapacitors over 1F aren't exactly rare, but they usually have low voltage ratings.

    Why do you think 1F is a limit?

    The farad is a unit of measurement, just like ohms, and inductance
