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. Ceramic capacitors are.

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.
Apart from the parameters discussed above (Emax, ΔP, Wrec, and η), temperature and frequency stability are also important for practical applications. In the future, high energy density ceramic capacitors will be placed closer to the core engine electronics to optimize the equivalent circuit resistance.
A single ceramic disc of about 3-6 mm can be used to reach very low capacitance. The dielectric constant (Dk) of ceramic capacitor dielectrics is very high, so relatively high capacitance can be obtained in small packaging. These capacitors are used in circuits where the required capacitance is very high.
The capacitance of ceramic capacitor dielectrics is impacted by temperature and applied voltage. They also have lower DC leakage current values and lower equivalent series resistance (ESR).
We will discuss more in class 2. ceramic capacitors chapter. Higher capacitance values for ceramic capacitors can be attained by using mixtures of ferroelectric materials like barium titanate together with specific oxides.
