What are the relevant knowledge of high-voltage ceramic capacitors?

High-temperature sintering is one of the most important processes of high-voltage ceramic capacitors. After one hundred tons of stamping and casting, and more than one thousand degrees of high temperature sintering, the inside of the high-voltage ceramic capacitor chip, the structure between the various molecules into a crystal structure. The next 6 hours of high temperature baking and 7 hours of heat preservation completely disrupted the internal structure of the crystal.






Then, in order to restore the structure of the chip and stabilize the characteristics of the chip, high-voltage ceramic capacitors need time to recover. Natural recovery (storage at room temperature) is better than 60 days. Moreover, products that have been stored for one year and two years have long periods of time as their outstanding performance. Therefore, a long recovery period is very helpful to the performance of the capacitor. A capacitor without a recovery period has poor voltage and current withstand performance. It is found through experiments that the loss angle value of high-voltage ceramic capacitors stored for a long time will become smaller and the high-frequency characteristics will be better.
