Welcome to the official website of Zhizhong Electronics Co., Ltd.Company focus: Ceramic Capacitor, Monolithic capacitor

Medium and high voltage ceramic capacitors are made by extruding high-dielectric constant capacitor ceramics (barium titanate titanium monoxide) into tubes, wafers or discs as the medium, and plating silver on the ceramics as electrodes by firing infiltration method. It is divided into high-frequency porcelain and low-frequency porcelain. Capacitors with small positive capacitance temperature coefficients are used in high-stability oscillation circuits as loop capacitors and pad capacitors. Low-frequency ceramic capacitors are limited to bypass or DC blocking in circuits with lower operating frequencies, or occasions where stability and loss are not high (including high frequency). Such capacitors are not suitable for use in pulse circuits because they are susceptible to breakdown by pulse voltage.
　　 Medium and high voltage ceramic capacitors are divided into two types: high-frequency ceramic and low-frequency ceramic. Capacitors with small positive capacitance temperature coefficients are used in high-stability oscillation circuits as loop capacitors and pad capacitors. Low-frequency ceramic capacitors are limited to bypass or DC blocking in circuits with lower operating frequencies, or occasions where stability and loss are not high (including high frequency). Such capacitors are not suitable for use in pulse circuits because they are susceptible to breakdown by pulse voltage. Medium and high voltage ceramic capacitors can be divided into plug-in and patch type according to different packages! According to the different mediums, it can be divided into Type I ceramic dielectric capacitors and Type II ceramic dielectric capacitors. Usually NP0, SL0, COG are Type I ceramic dielectric capacitors, X7R, X5R, Y5U, Y5V are Type II ceramic dielectric capacitors, and the capacity of similar ceramic capacitors. The stability is very good, basically does not change with changes in temperature, voltage, time, etc., but the general capacity is very small, while the stability of the capacity of type II ceramic dielectric capacitors is very poor, and the range of changes with temperature, voltage, and time is large, so generally Used in occasions that do not require high capacity stability, such as filtering!
