Many engineers and researchers will ask us: Mr. He, what is the service life of your high voltage ceramic capacitors? How did this result come about?
3. Partial discharge. This is the bottleneck of many domestic manufacturers. The larger the size, the more difficult the partial discharge is to handle. But after our long-term market practice, it is found that the closer the partial discharge is to 0 PC, the better the performance and life of all aspects. For example, in high-frequency pulse circuit, the smaller the partial discharge is, the stronger the ability to withstand high-frequency pulse is, that is, the longer the life. 4. It also includes the current capacity, which has an effect on the life of capacitors. If the overcurrent is large, the life of capacitors will be long. Looking at the above several most prominent factors affecting the use of high voltage capacitors, we can easily see that in order to make the best products, we must achieve high AC voltage, good frequency characteristics, small partial discharge and strong over-current capability. However, many customers often ignore some factors, or the producers think that as long as some factors meet customer requirements, it is wrong. For example, military products, although using DC voltage, do not require partial discharge, but in practical application, high AC voltage, small partial discharge, to ensure better life and performance. This is like athletes in swimming competitions, not only smooth posture science, more importantly, physical strength, the best explosive force is king!
