What is a ceramic capacitor made of.

The electrode ink is made from a metal powder that is mixed with solvents and ceramic material to make the electrode ink. A capacitor consists of two conductors separated by a non conductive region. Characteristics precision and tolerances. 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 type i ceramic capacitor generally has a dielectric made from a mixture of metal oxides and titanates. These are used in resonant circuits filters and. The two most common types are multi layer ceramic capacitors and ceramic disc capacitors. 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 capacitors are classified as type i type ii or type iii. They have high insulation resistance and lower frequency losses and maintain a stable capacity even when voltage varies. There are two classes of ceramic capacitors available today. 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.

The electrodes are now printed onto the ceramic sheets using a screen printing process. Ceramic capacitor definition a ceramic capacitor is a capacitor which uses a ceramic material as the dielectric. 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.

From coulomb s law a charge on one conductor will exert a. The ceramic capacitor is made by making a finely grounded powder of a dielectric material which is either paraelectric material like the titanium.
