High-voltage chip capacitor, also known as ceramic multilayer chip capacitor, is made by ceramic powder production technology, with precious metal alladium inside, and silver plated on ceramic as electrode by high-temperature sintering method. Products are divided into two materials: high-frequency porcelain NPO(COG) and low-frequency porcelain X7R. NPO has small package size, high temperature resistance coefficient capacitor and high frequency performance, which is used in high stability oscillation circuit as filter capacitor of circuit. X7R ceramic capacitors are limited to bypass or isolate DC in circuits with normal operating frequency, or they are not suitable for use in AC pulse circuits because they are easily broken down by pulse voltage, so they are not recommended for use in AC circuits.

Capacitance characteristics of high voltage patch
(1) the capacitance value can be greatly enlarged by using the thin layer and multilayer lamination technology of the dielectric layer of the SMD ceramic capacitor;
(2) The monolithic structure ensures excellent mechanical strength and reliability;
(3) High precision and high automatic assembly precision;
(4) Because it is only composed of ceramics and metals, it will not gradually decline even in high and low temperature environments, and it has strong reliability and stability;
(5) The characteristic of low distributed capacitor can complete the circuit design close to the theoretical value;
(6) The residual induction coefficient is small, ensuring good frequency characteristics;
(7) Capacitors have been obtained in the field of electrolytic capacitors, which prolongs the service life, resulting in a highly reliable power supply;
(8) Low 8)ESR and good frequency characteristics are most suitable for high frequency and high density power supplies;

Application field of high voltage chip capacitor
High-voltage patch capacitor is mainly used in power filter, power buck, double voltage and surge absorption protection circuit. The basic working principle is charging and discharging, and of course it also has the functions of rectification and vibration. This is used for power circuit to realize bypass, coupler, filter and energy storage. Modular power supply, electric tools, smart home, smart home appliances, LED lighting series (incandescent lamp, tungsten lamp, G4, G9 lamp, COB lamp, bubble lamp), resistance capacitor step-down power supply, automotive electronics, automotive xenon lamp (HID electron ion stabilizer), and negative. Ion generators, energy-saving lamps, high-frequency electrodeless lamps, electronic ballasts and other products chip varistor products are specially used in the fields of computers, communication products, network products, vehicle-mounted equipment, automotive electronics, safety products, intelligent products, captive products, lighting appliances, industrial control equipment, toys and so on.
