Ceramic capacitor is a fixed value capacitor in which 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.

Scope and Importance:
In future as the Bi2Zn2/3Nb4/3O7 (m-BZN) and the Ti –doped m-BZN ceramics are found to be able to get sintered below 1000°C, efforts can be initiated to reduce the sintering temperature of these materials by adding some sintering aids and study their microwave dielectric characteristics. So that these materials can be effectively used for LTCC applications. The growth and dielectric properties of these thin films directly on SiO2/Si wafers can be explored further. The nano mechanical properties of these thin films are interesting to study
Ceramic capacitors are divided into two application classes
Class 1 ceramic capacitors offer high stability and low losses for resonant circuit applications.
Class 2 ceramic capacitors offer high volumetric efficiency for buffer, by-pass and coupling applications.
Ceramic capacitors, especially the multilayer style (MLCC), are the most produced and used capacitors in electronic equipment that incorporate approximately one trillion pieces (1000 billion pieces) per year
Class 1 ceramic capacitors are accurate, temperature-compensating capacitors. They offer the most stable voltage, temperature, and to some extent, frequency. They have the lowest losses and therefore are especially suited for resonant circuit applications where stability is essential or where a precisely defined temperature coefficient is required, for example in compensating temperature effects for a circuit. The basic materials of class 1 ceramic capacitors are composed of a mixture of finely ground granules of Para electric materials such as Titanium dioxide TiO
2), modified by additives of Zinc, Zirconium, Niobium, Magnesium, Tantalum, Cobalt and Strontium, which are necessary to achieve the capacitor’s desired linear characteristics.
Class 2 ceramic capacitors have a dielectric with a high permittivity and therefore a better volumetric efficiency than class 1 capacitors, but lower accuracy and stability. The ceramic dielectric is characterized by a nonlinear change of capacitance over the temperature range. The capacitance value also depends on the applied voltage. They are suitable for bypass, coupling and decoupling applications or for frequency discriminating circuits where low losses and high stability of capacitance are less important.
Class 3 ceramic capacitors have very high permittivity, up to 50,000 and therefore a better volumetric efficiency than class 2 capacitors. However, these capacitors have worse electrical characteristics, including lower accuracy and stability. The dielectric is characterized by very high nonlinear change of capacitance over the temperature range. The capacitance value additionally depends on the voltage applied. As well, they have very high losses and age over time.Market Analysis:
