High voltage porcelain capacitor is a kind of circular plate capacitor with ceramic material as the medium, which has the characteristics of high voltage resistance and low loss, and is widely used in high voltage circuit. Its main function is to eliminate high-frequency interference, which is suitable for negative ion products, lasers, X-ray machines, control and measurement equipment, high voltage package, igniter, generator, transformer, power equipment, voltage doubling module, welding machine, electrostatic spraying and other electromechanical equipment requiring high voltage and high frequency.
Advantages of high voltage chip capacitors include:
High voltage resistance: can withstand high DC voltage, common voltage values are 3.6KV, 6.5KV, 7.2KV, 10KV, 12KV, 13KV, 15KV, 20KV and so on.
Low loss: Low dielectric loss in high-voltage bypass and coupling circuits, especially suitable for use in television receivers and scanning circuits.
Good frequency characteristics: High stability, suitable for high frequency applications.
Special series structure: suitable for long-term operation with high voltage and high reliability.
In addition, the working principle of high voltage porcelain chip capacitors is based on the interaction of electric fields. When a voltage is applied between the two metal electrodes of the capacitor, an electric field is generated in the medium and causes the polymer charge in the medium to form the electric field of the capacitor, thus storing electrical energy.
High voltage ceramic capacitors play an important role in many high voltage circuits, such as TV sets, computer monitors, X-ray generators and so on, because of their advantages of high voltage resistance, low loss and high stability.
