What is a ceramic chip capacitor?
The ceramic chip capacitor is formed by extruding a high dielectric constant capacitor ceramic barium titanate titanate into a circular tube, a disk or a disk as a medium, and plating the silver on the ceramic as an electrode by a fire infiltration method. It is divided into high frequency porcelain and low frequency porcelain.
Ceramic capacitors can be divided into plug-ins and patches according to the package. According to different media, it can be divided into class I ceramic capacitor and class II ceramic dielectric I capacitor, usually NP0, SL0, COG is class I ceramic dielectric capacitor, X7R, X5R, Y5U, Y5V is class II ceramic dielectric capacitor, class I porcelain dielectric Capacitance capacity stability is very good, basically does not change with changes in temperature, voltage, time, etc., but the general capacity is very small, and the capacity stability of the class II ceramic dielectric capacitor is very poor, with a large change in temperature, voltage, time, Therefore, it is generally used in applications where capacity stability is not high, such as filtering.
Use of ceramic chip capacitor
SMD ceramic capacitors used in high-power, high-voltage applications require small size, high withstand voltage and good frequency characteristics. With the advancement of materials, electrodes and manufacturing technology, the development of high-voltage ceramic capacitors has made great progress and has been widely used. According to the Electronic House, SMD ceramic capacitors have become an indispensable component of high-power high-voltage electronic products. The use of chip ceramic capacitors is mainly divided into power equipment for power transmission and distribution systems and equipment for processing pulse energy.
