Ceramic Capacitors: These capacitors are made of ceramic materials and are widely used due to their small size and stability.

Electrolytic Capacitors: These capacitors use an electrolyte as one of their electrodes, offering high capacitance values in a compact size. They are polarized, meaning they must be connected in a specific orientation.

Tantalum Capacitors: Tantalum capacitors are a type of electrolytic capacitor known for their high capacitance density and stability. They are commonly used in applications where size is a constraint.

Film Capacitors: Film capacitors use a thin plastic film as the dielectric. They come in various types such as polyester (Mylar), polypropylene, and polycarbonate. Film capacitors offer good stability and are often used in high-performance applications.

Aluminum Electrolytic Capacitors: These capacitors use an aluminum oxide layer as the dielectric. They are polarized and commonly used in power supply filtering applications.

Supercapacitors (Ultracapacitors): Supercapacitors store energy electrostatically and offer much higher capacitance values compared to traditional capacitors. They are used in applications where rapid energy storage and release are required, such as regenerative braking systems in vehicles.

Variable Capacitors: These capacitors have a capacitance value that can be adjusted manually or electronically. They are often used in tuning circuits, such as in radios and oscillators.

Mica Capacitors: Mica capacitors use mica as the dielectric material and offer high stability and low loss. They are commonly used in high-frequency and high-voltage applications.

Polystyrene Capacitors: Polystyrene capacitors use polystyrene as the dielectric material and offer good stability and low dielectric absorption. They are often used in precision electronic circuits.

Glass Capacitors: These capacitors use glass as the dielectric material and are known for their high stability and low losses. They are used in specialized applications where reliability is critical.

Paper Capacitors: Paper capacitors use paper as the dielectric material and are often impregnated with oil for improved performance. They are less common today due to their relatively large size and lower reliability compared to modern capacitors.
