Explaining Capacitors and the Different Types | DigiKey
On one hand, ripple voltages imposed across a capacitor can be translated into bothersome audible noise; on the other, external mechanical vibrations can be coupled as signals into an electronic circuit. Ceramic capacitors based on class 1 dielectrics are affected the least, as these dielectrics exhibit little to no piezoelectric effect.
A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate …

How to choose the right capacitor for any application
Decoupling capacitors. Decoupling capacitors are usually connected between the DC power supply (e.g., V CC) and ground the case of decoupling capacitors used with digital integrated circuits, the energy storage of the decoupling capacitor is used to hold the voltage across the digital integrated circuit constant.
The equivalent capacitor circuit shown here accounts for excitation of resonances by a fast transient, including an ESD event. Because of the voltage rating issue, and due to the inductance of typical high-voltage capacitors requiring large case sizes, it''s best to avoid capacitors as a form of ESD protection, especially on signal lines.
