Pure ST ceramics exhibited a relative dielectric permittivity of 300, a breakdown electric field of 1600 kV/mm, and a dielectric loss of 0.01 at RT, and are utilized for integrated circuit applications [39, 42, 46]. Chemical modifications have been adopted to enhance the energy storage properties in ST ceramic capacitors.
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).
Also, there are classification methods for class 1, class 2, and class 3. Compared with other capacitors, general ceramic capacitors have the advantages of higher use temperature, large specific capacity, good humidity resistance, and small dielectric loss. The temperature coefficient of capacitance can also be selected in a wide range.
