Ceramic Capacitor Use And Function

Such capacitors which have ceramic material as a dielectric are known as ceramic capacitors.

Ceramic capacitor use and function.

Ceramic capacitor definition a ceramic capacitor is a capacitor which uses a ceramic material as the dielectric. The capacitors in which the ceramic material such a paralectric titanium oxide or ferroelectic is used as the insulating material or dielectric is known as the ceramic capacitors. A ceramic capacitor is a fixed value capacitor where the ceramic material acts as the dielectric it is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes the composition of the ceramic material defines the electrical behavior and therefore applications. The function of these capacitors are decided according to the electrical characteristics of the used ceramic material.

From coulomb s law a charge on one conductor will exert a. A ceramic capacitor is a type of capacitor which is manufactured using ceramic material as the dielectric medium. There are two classes of ceramic capacitors available today. Ceramic disc capacitors have a capacitance value of about10pf to 100μf with a wide variety of voltage ratings between 16v to 15 kv and more.

Class 1 and class 2. They are also sometimes. Non polarity device means the capacitor has no polarities. The non conductive region can either be a vacuum or an electrical insulator material known as a dielectric examples of dielectric media are glass air paper plastic ceramic and even a semiconductor depletion region chemically identical to the conductors.

Ceramic disc capacitors are made by coating a ceramic disc with silver contacts on both sides as shown above illustrates. The size of the ceramic capacitors is very small as compared to the other capacitors due to their high dielectric constant. Following is the symbol for ceramic capacitor. Ceramic capacitors can store a very small amount of electrical energy that is why they are available in very small values such as microfarad millifarad nanofarad picofarad etc.

Characteristics precision and tolerances. Ceramic capacitors can be used anywhere a capacitor having very low internal parasitic inductance is required. Different types of ceramic capacitors. The ceramic capacitor is a non polarity device which is found commonly in every electrical device and the dielectric material that is used in the capacitor is a ceramic material.

The two most common types are multi layer ceramic capacitors and ceramic disc capacitors.
