What is a capacitor used for in a DC power supply?

Capacitors are used to filter out noise from a DC power supply. By connecting a capacitor across the DC power supply, high-frequency noise will be shorted to the ground while the DC signal passes through unaffected. When a circuit with an inductor connected is abruptly opened, the current passing through the coil diminishes quickly.

Conakry electrostatic capacitor test

When static electricity charged to people or equipment is discharged to electronic devices or components, an electromagnetic energy shock is applied; therefore capacitors must have a constant ESD resistance or more. There are three test methods for ESD resistance: (1) HBM, (2) MM, and (3) CDM as shown in the. . The capacitance of the test capacitor affects the voltage that occurs on both sides of a capacitor. The following relationship is established. [pdf]
