Ceramic capacitors are also known as porcelain dielectric capacitors or monolithic capacitors. As the name suggests, ceramic capacitor is a capacitor whose dielectric material is ceramic. According to the different ceramic materials, the price of film capacitor, this capacitor can be divided into two types of low frequency porcelain capacitors with a capacity of 1 to 300 pF and high frequency porcelain capacitors with a capacity of 300-22,000 pF. According to the classification of structure, it can be divided into picture capacitor, tube capacitor, rectangular capacitor, chip capacitor, core-piercing capacitor and so on.

With the rapid development of electronic industry, there is an urgent need to develop high voltage ceramic capacitors with high breakdown voltage, low loss, small size and high reliability. In the past 20 years, the successful high-voltage ceramic capacitors developed at home and abroad have been widely used in electric power system, laser power supply, tape recorder, color TV, electronic microscope, copier, office automation equipment, astronautics, missiles, navigation and so on.
The ceramic material of high-voltage ceramic capacitors mainly has two categories: barium titanate and strontium titanate. Barium titanate-based ceramic materials have the advantages of high dielectric coefficient and good AC voltage resistance characteristics, but also has the disadvantages of capacitance change rate with the rise of dielectric temperature, insulation resistance decreases. The Curie temperature of strontium titanate crystal is -250℃, and it is cubic crystal system chalcogenide structure at room temperature, which is paraelectric and does not have spontaneous polarization phenomenon.
