All Types of Capacitor Symbol and Diagram


A Capacitor is a device that stores electrical energy in form of an electric charge in an electrical field. A capacitor is very well known as a passive electrical or electronic component. A capacitor is a two-terminal device and the property or effect of a capacitor is called capacitance. The capacitor is also known as Condensor.

The capacitor is a very useful component and it used in almost all electrical and electronic circuits. The main function of a capacitor is to store electrical energy. A capacitor is used for energy storing, power factor improvement, and filter circuits. There are various types of capacitors according to their nature, polarity, and construction. In this article, we are going to see all types of capacitor symbols and diagrams.

The different types of capacitor are,

  • Electrolytic Capacitor
  • Ceramic Capacitor
  • Polarized Capacitor
  • Non-Polarized Capacitor
  • Fixed Capacitor
  • Variable Capacitor
  • Trimmer Capacitor




Electrolytic Capacitor is made of aluminum or tantalum plate with an oxide dielectric layer. The other electrode is a liquid electrolyte. Electrolytic capacitors are polarized capacitors. Electrolytic capacitors provide high capacitance but they have low tolerance and high explosion risk. Here you can see the symbol of the electrolytic capacitor.

Ceramic capacitors are very cheap and compact in design. They are most suitable for high-frequency applications. The ceramic capacitor only provides a low capacitance value. Ceramic capacitors are nonpolarized capacitors. Here you can see the symbol of ceramic capacitor.

Polarized capacitors are unable to work with varying polarity power supply. They have specific positive and negative terminals. When the positive terminal of the capacitor is connected to the positive terminal of the power supply and the negative terminal of the capacitor is connected to the negative terminal of the power supply, it will work properly. Electrolytic Capacitor, Supercapacitor are examples of Polarised Capacitor. Here, you can see the symbol of the polarised capacitor.

Non Polarized capacitors are those which can work with varying polarity power supply. They have not any specific positive or negative terminal. Ceramic capacitors are examples of non-polarised capacitors. Here, you can see the symbol of the Non polarised capacitor.

A fixed capacitor always provides a constant capacitance value. Its capacitance cannot be varied or change. Here you can see the symbol of Fixed Capacitor. Normal compact electrolytic capacitors and ceramic capacitors are examples of Fixed capacitors.

A variable capacitor can provide different capacitance values as per our requirements. We can vary its capacitance value anytime. Here, you can see the symbol of the variable capacitor.

Trimmer capacitor is also one type of variable capacitor. It uses the trimming of the dielectric medium of the capacitor to change the capacitance value. Here, you can see the symbol of the Trimmer Capacitor.
