Ceramic chip capacitors are also called ceramic or monolithic capacitors. As the name implies, ceramic medium is made of ceramic medium material. According to the structure, it can be divided into mirror image, tubular, rectangular, sheet, overcurrent capacitor, etc. Low-voltage ceramics have the characteristics of high dielectric constant, small volume and large capacity. There are two basic methods to realize the miniaturization of the separation capacitor module: increasing the dielectric constant of the dielectric material as much as possible and making the thickness of the dielectric layer as thin as possible. First of all, ferroelectric ceramics are easy to break when they are thin, which makes it difficult to operate in actual production.
And the dielectric of ceramic patch capacitor is made of ceramic dielectric material. According to different ceramic materials, it can be divided into 1~300~22000pf. According to the structure, it can be divided into mirror image, tubular, rectangular, sheet, overcurrent, etc. The dielectric material of ceramic capacitor is ceramic dielectric, which has good heat resistance, not easy aging, acid, alkali and salt corrosion resistance and good corrosion resistance. Low-voltage ceramics have the characteristics of high dielectric constant, small volume and large capacity. Ceramic capacitors have good insulation performance and high voltage resistance, and do not change with temperature, voltage and time.
Semiconductor ceramic capacitors and surface ceramic capacitors. Miniaturization of capacitors means that capacitors can obtain large capacity in a small volume, which is one of the development trends of capacitors. There are two basic methods to realize the miniaturization of the separation capacitor module: the thickness of the dielectric layer with the dielectric constant of the dielectric material is as thin as possible. Among ceramic materials, the dielectric constant of ferroelectric ceramics is very high, but it is difficult to thin the dielectric when making common ferroelectric ceramic capacitors with ferroelectric ceramics. First of all, ferroelectric ceramics are easy to break when they are thin, which makes it difficult to operate in actual production. Secondly, when the ceramic medium is thin, it is easy to produce various structural depressions, and the production technology is very difficult.
