High voltage ceramic capacitor

Introduction to product description: High-voltage ceramic capacitors are usually used in high-voltage applications. Ceramics can be divided into one type, two types and three types. The first-level porcelain np0 has good temperature characteristics, frequency characteristics and voltage characteristics, low dielectric constant, and small capacity; second-level porcelain has better temperature and voltage characteristics, followed by X7R; third-level porcelain has higher dielectric properties The electric constant, so its capacity can be large, but its temperature and voltage characteristics are not very good. Ceramic capacitors are generally small in size. In addition, another important feature of ceramic capacitors is emphasized: after a ceramic capacitor breaks down, it is often in a short-circuit state. After a film capacitor fails, it is usually in an open circuit state.

Product Series

The typical function of high-voltage ceramic capacitors is to eliminate high-frequency interference. Widely used in negative ion products, lasers, X-ray machines, control and measurement equipment, high-voltage complete sets of equipment, igniters, generators, transformers, power equipment, voltage doubling modules, welding machines, electrostatic spraying and other electromechanical equipment that require high-voltage and high-frequency.

Product Features

1. High-voltage ceramic capacitors have wear-resistant DC and high-voltage characteristics, and are suitable for high-voltage bypass and coupling circuits. The low-loss high-voltage disc has low dielectric loss. As long as high-voltage ceramic capacitors are aimed at high frequencies, high-voltage ceramic capacitors depend on the application. The typical role is to eliminate high-frequency interference.

2. High-voltage ceramic capacitors used in high-power and high-voltage fields require small size, high voltage resistance, and good frequency characteristics. In recent years, with the advancement of materials, electrodes and manufacturing technology, the development of high-voltage ceramic capacitors has made considerable progress and has been widely used. High-voltage ceramic capacitors have become one of the indispensable components of high-power, high-voltage electronic products.

3. The applications of high-voltage ceramic capacitors are mainly divided into power supply equipment for power transmission and distribution systems and pulse energy processing equipment. Due to the particularity of the power system and the harsh environment, the capacitor is required to have super stability, that is, the rate of change is small; at the same time, products such as measurement, energy storage, and voltage division require high accuracy, which is important for the partial discharge of high-voltage ceramic capacitors in this environment. There are extremely strict requirements: zero partial discharge.
