A capacitor is an electronic component that stores and releases electrical energy. It has two plates separated by an insulator. When you apply voltage to it, one plate gets a positive charge, and the other gets a negative charge. It stores this charge and can release it when needed.
Capacitors come in many types, cases, and values. Their basic function falls into two broad categories:
- Supporting adequate power delivery by storing electrical energy for nearby integrated circuit (IC) devices.
- Providing filtration of unwanted spurious circuit noise.
