All Types of Capacitor Symbol and Diagram

A Capacitor is a device that stores electrical energy in the 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 the Condensor. 

Learning and understanding the symbols for different capacitor types is a fundamental aspect of electrical and electronics education. That is why in this article, we are going to see all types of capacitor symbols and diagrams. There are various types of capacitors. All of them are not possible to explain but here you can see all the most important and most usable capacitor symbols.

The capacitor is a very useful component and it is 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 storage, 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 capacitors are,

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

Electrolytic Capacitor Symbol

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 Capacitor Symbol

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 Capacitor Symbol

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 Capacitors, and Supercapacitors are examples of Polarised Capacitors. Here, you can see the symbol of the polarised capacitor.

Non Polarized Capacitor Symbol

Non-polarized capacitors are those which can work with varying polarity power supply. They do not have 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.

Fixed Capacitor Symbol

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

Variable Capacitor Symbol

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. The symbol used to represent a variable capacitor in circuit diagrams or schematics typically consists of two parallel lines with an arrow or a straight line crossing between them. The arrow or straight line indicates that the capacitor is adjustable and its capacitance value can be varied.

Trimmer Capacitor Symbol

A 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.

Preset Capacitor Symbol

Here, you can see the symbol of Preset Capacitor. The main difference between Trimmer Capacitor and Preset Capacitor is the Trimmer capacitors are adjustable by the user to fine-tune the capacitance value, while preset capacitors come pre-adjusted to a specific capacitance value and are not intended for further adjustment by the end user.
