Understanding Capacitors: Basics and Classification
Keywords: Capacitors, basics, classification
Capacitors are passive electronic components used in a wide range of applications, including power supply filtering, signal coupling, frequency tuning, and timing circuits. In this article, we will introduce the basics of capacitor and their classification.
What are Capacitors?
Capacitors are electronic components that store electrical energy in an electric field between two conductive plates separated by an insulating material called a dielectric. Capacitor are characterized by their capacitance, which is the amount of charge that can be stored per unit of voltage.
Classification of Capacitor:
Capacitors are classified based on their dielectric material, construction, and application. Some common types of capacitor include:
Manufacturers make ceramic capacitor by coating ceramic discs with metal electrodes. They are small, inexpensive, and widely used in high-frequency applications.
Manufacturers produce electrolytic capacitor as polarized capacitor that use an electrolyte as the dielectric. Engineers commonly use them in power supply filtering and audio applications.
Film Capacitor: Film capacitor use a thin polymer film as the dielectric. Manufacturers offer a wide range of capacitances for film capacitor, which engineers commonly use in timing circuits and audio applications.
Manufacturers produce tantalum capacitor as polarized capacitor that use tantalum metal as the electrodes. They are small, reliable, and commonly used in portable electronic devices.
Supercapacitors: Supercapacitors are high-capacity capacitor that can store a large amount of charge. Engineers commonly use them in energy storage applications.
In conclusion, engineers and designers widely use capacitors as essential electronic components in a broad range of applications.Capacitor are classified based on their dielectric material, construction, and application. By understanding the basics of capacitor and their classification, designers can select the appropriate capacitor for their specific application.
