Basically, a capacitor is a device that stores electrical energy by placing two conductors close together and cover them. Capacitors have a broad range of uses. In other words, Capacitors store electrical energy in an electrical field. They are used in digital circuits, for example, to stop the loss of information in large computer memory cells due to a short loss of electrical power; by storing electric energy in such capacitors, the information in the memory cells remains unharmed. Capacitors are much more useful as filters for blocking faulty electric signals. We can help your design team develop a time sensitive design at the early stage of a project or in the later stages of a project.



To determine how much energy is storing in a capacitor the main factors which we consider are voltage and charge. Super capacitors are capable of storing a huge amount of energy. Medical personnel use a defibrillator in a movie entertainment so the energy from a capacitor is normally used to send an electric current through the patient’s heart to get it to beat.

Capacitors of Various Types:

1. Electrolytic Capacitor
2. Mica Capacitor
3. Paper Capacitor
4. Film Capacitor
5. Non-Polarized Capacitor
6. Ceramic Capacitor

Electrolytic capacitors – The electrodes here are made as a semi-liquid electrolyte solution in the form of a jelly or paste, instead of using a thin metallic film.

Mica Capacitor-The dielectric used in silver mica capacitors is a group of natural minerals. Due to its specific crystalline formation binding, and the characteristic layers it has. Minerals such as mica are electrically, chemically and mechanically strong.

Paper Capacitor -In addition to its simple process, paper capacitors have a low production cost since they separate thin layer of metal foil, and have paper as their dielectric material.

Film Capacitor- To produce the film capacitor it is important to make the extremely thin film first.

Non-Polarized Capacitors- It is necessary to connect the non polarized capacitor to the signal or electrical power supply in series or parallel.

Ceramic Capacitor- To make the capacitors as an insulator the first material using in it is ceramic.


In the final analysis, many of the major capacitor manufacturers have stopped manufacturing completely or discontinued entire product lines in recent decades, causing their capacitors to become outdated. You should call the manufacturer or a trusted distributor if you’re not sure an item is available. Keep in mind that the original manufacturer may not be too helpful when it comes to out dated parts. In this article, we discussed the various types of capacitors and their applications. After reading this article, I hope you get some basic understanding of capacitor types.
