Disc Ceramic Capacitor Function

- November 17, 2019

Ceramic disc capacitors have a capacitance value of 10pf to 100mf with a wide variety of voltage ratings between 16 volts to 15 kv and more. The ceramic disc capacitor is pretty much the standard type used in the tone control circuit.

Multi layer ceramic capacitor mlcc.

Disc ceramic capacitor function. It is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes. Ceramic capacitors can also be used as a general purpose capacitor because of their non polarity and are available in a large variety of capacitances voltage ratings and sizes. Mlccs are used instead if capacitance values allow.

Fixed leaded disc and multilayer ceramic chip capacitors mlcc a ceramic capacitor is a fixed value capacitor where the ceramic material acts as the dielectric. Ceramic disc capacitors have a low loss factor a reasonable level of stability and work well with high frequencies. The area of a ceramic disc or dielectric and spacing between the silver electrodes also determines the capacitance of the ceramic disc capacitor.

As a charge is driven onto one plate of a capacitor the extra charge there builds up an electric field. What is ceramic capacitor. 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 used across brush dc motors to minimize rf noise. The ceramic capacitor is made by making a finely grounded powder of a dielectric material which is either paraelectric material like the titanium dioxide or ferroelectic material like the barium titanate. A ceramic disc capacitor is a capacitor constructed with a ceramic disc as the dielectric.

This type of capacitor is very inexpensive to build and most look very much like figure 1. Youll recall that the basic definition of a capacitor is two conductors separated by an insulator dielectric of some kind. The function of these capacitors are decided according to the electrical characteristics of the used ceramic material.

Such capacitors which have ceramic material as a dielectric are known as ceramic capacitors. Ceramic disc capacitors are usually through hole components and are falling out of favor due to their size. A protective coating is applied to the ceramic disc capacitor to protect it from heat.

The size of the ceramic capacitors is very small as compared to the other capacitors due to their high dielectric constant.
