Explore Types of Capacitors and Uses

Ceramic capacitors

Ceramic capacitors have low equivalent self-inductance, equivalent series resistance (ESR), and dielectric absorption. On the flip side, some ceramic capacitors exhibit the piezoelectric effect, making them electrically sensitive to shock and vibrations. Ceramic capacitors are widely used for smoothing, filtering, coupling, and decoupling.

Tantalum capacitors

Tantalum capacitors have very low equivalent series resistance (ESR) and leakage current. These passive components are mostly available in low capacitance and low voltage values. Tantalum capacitors are commonly used for bypassing applications in power supply systems.

Aluminum electrolytic capacitors

Aluminum electrolytic capacitors can be broadly categorized into two classes: solid electrolyte and non-solid electrolyte capacitors. These capacitors are available in a wide range of capacitance, sizes, and voltage values. They are wide used in power supply and converter circuits for smoothing and DC link applications.

Film capacitors

A film capacitor utilizes a thin plastic film as the dielectric material between its metal electrodes. Common types of film capacitors include polyester, polypropylene, polystyrene, polycarbonate, Teflon, and polysulfone film capacitors. Film capacitors are used in a variety of applications including filtering and coupling in electronic circuits.


1F supercapacitors

Supercapacitors, also known as ultracapacitors or electric double layer capacitors (EDLC), bridge the gap between traditional capacitors and rechargeable batteries. A supercapacitor can deliver and absorb energy rapidly. These components have relatively high capacitance values compared to regular capacitors. They can provide bursts of energy in short durations.


Mica capacitors

A mica capacitor is a type of capacitor that uses mica as the dielectric material. These capacitors are known for their high stability, high quality factor, and high temperature tolerance. Mica capacitors are commonly employed in high-frequency applications and radio frequency circuits where precise capacitance values are crucial.
