Ceramic Capacitor Use And Function

A ceramic capacitor is a type of capacitor which is manufactured using ceramic material as the dielectric medium.
Ceramic capacitor use and function. Most commonly they are used as powersupply bypass 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 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. Ceramic disc capacitors are made by coating a ceramic disc with silver contacts on both sides as shown above illustrates.
There are two classes of ceramic capacitors available today. Ceramic capacitors can be used anywhere a capacitor having very low internal parasitic inductance is required. 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. A capacitor consists of two conductors separated by a non conductive region.
Different types of ceramic capacitors. The ceramic capacitor is made by making a finely grounded powder of a dielectric material which is either paraelectric material like the titanium. Such capacitors which have ceramic material as a dielectric are known as ceramic capacitors. The function of these capacitors are decided according to the electrical characteristics of the used ceramic material.
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. 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. From coulomb s law a charge on one conductor will exert a. Following is the symbol for ceramic capacitor.
They are also sometimes. The size of the ceramic capacitors is very small as compared to the other capacitors due to their high dielectric constant. Class 1 and class 2. Ceramic capacitor definition a ceramic capacitor is a capacitor which uses a ceramic material as the dielectric.
