Capacitors are devices that store an electrical charge, and they consist of two metallic plates that are separated by an insulating material called a dielectric. This dielectric greatly increases the capacitance of the capacitor and enables it to store more charge than it would normally be able to. The size of the plates as well as the type of dielectric used determines how much charge can be stored in the capacitor.

Capacitors can store energy and release it rapidly when needed, making them useful for smoothing out voltage fluctuations, filtering out noise, and providing temporary power during power interruptions.

You can achieve your impedance and capacitance goals by connecting multiple capacitors in series or parallel. Series capacitors are useful when you need to achieve a higher voltage rating or when you want to divide a high voltage into smaller voltages across individual capacitors. Parallel connection helps when you want to increase the total capacitance or when you need to share the current among multiple capacitors to handle higher current levels.

There are different types of capacitors available, including electrolytic capacitors, ceramic capacitors, tantalum capacitors, film capacitors, and many others.
