A couple reasons come to mind. Lower ESR. The effective ESR of the capacitors follows the parallel resistor rule. For example, if one capacitor''s ESR is 1 Ohm, putting ten in parallel makes the effective ESR of the capacitor bank ten times smaller.

In actual operating conditions, the self-healing behaviour of capacitors is influenced by the operating conditions of the power grid. When the equivalent capacitance of the grid is large, the self-healing current will increase accordingly, leading to an increase in capacitance loss caused by self-healing, and consequently, a shorter lifespan of ...

A capacitor is a device used to store electric charge. Capacitors have applications ranging from filtering static out of radio reception to energy storage in heart defibrillators. Typically, commercial capacitors have two conducting parts close to one another, but not touching, such as those in Figure (PageIndex{1}).
A capacitor is a device used to store electrical charge and electrical energy. It consists of at least two electrical conductors separated by a distance. (Note that such electrical conductors are sometimes referred to as "electrodes," but more correctly, they are "capacitor plates.") The space between capacitors may simply be a vacuum ...

Power capacitors are constructed of several smaller capacitors commonly referred to as "elements," "windings" or "packs." These elements are formed from multiple layers of aluminum foil (conductors) and polypropylene film (dielectric) wound together. When interconnected, multiple elements combine to function as a single capacitor unit.
For a given capacitor, the ratio of the charge stored in the capacitor to the voltage difference between the plates of the capacitor always remains the same. Capacitance is determined by the geometry of the capacitor and the materials that it is made from. For a parallel-plate capacitor with nothing between its plates, the capacitance is given by

Decoupling capacitors are an integral part of any PCB design as they help to mitigate noise and stabilize voltage levels. These capacitors are strategically placed near integrated circuits (ICs) to provide a low-impedance path for high-frequency noise generated by the ICs. By reducing noise, decoupling capacitors enhance the overall performance …

$begingroup$ @Majenko: The point is to reduce the high frequencies enough so that the active circuit in a voltage regulator can handle the remaining ones. Usually up to a few 10s of kHz is OK. For example, I often use some 950nH 600mOhm 200mA 0805 ferrites. With 22uF capacitance following these, you get one pole at 12 kHz from the R-C action, and …
