 Capacitors and classification

Capacitors are passive electronic components that store electrical energy in an electric field. They are used in a wide variety of electrical and electronic applications, and are classified based on a number of factors, including the type of dielectric material used, the physical construction of the capacitor, and the intended application of the capacitor.

Some common types of capacitors include:

  • Ceramic capacitors: These are made using ceramic materials as the dielectric, and are typically small, inexpensive, and widely used in electronic circuits.

  • Electrolytic capacitors: These use an electrolyte as the dielectric, and are typically used in applications requiring large capacitance values, such as power supplies and audio equipment.

  • Film capacitors: These use a thin plastic or metal film as the dielectric, and are known for their stability and precision. They are used in applications requiring high-frequency or high-voltage capabilities.

  • Tantalum capacitors: These are similar to electrolytic capacitors, but use tantalum as the anode and have a higher capacitance per volume. They are used in applications requiring high capacitance and small size.

  • Supercapacitor: also called ultracapacitor, EDLC. They are known for their high energy density and fast charging and discharging abilities, They are used in applications requiring high power density, such as regenerative braking in hybrid electric vehicles, wind and solar energy storage.

This is not an exhaustive list of all the classification of capacitors but the most common and basic ones.
