How to calculate the withstand voltage of high voltage ceramic capacitor

A few days ago, when editing and communicating with customers, he asked, "How is the withstand voltage of your high-voltage ceramic capacitors calculated?"

Answer: The test voltage of our company is a multiple of the rated voltage as follows: 1.CLASS I and II (50V-500V) is 3 times; 2.CLASS III (1KV-2KV) is 2 times; 3.3KV-4KV is 1.5 times; 4.5 KV-6KV is 1.2 times; 5.8KV is 1.0 times. The average imprinting time is 1-5 seconds, and the charging and discharging current is limited to 50MA or less.

“What is the difference between high-voltage ceramic capacitor blue and earth yellow?”

Answer: The blue color is epoxy encapsulation, which has good moisture resistance and good withstand voltage. The khaki is wet-encapsulated, which is susceptible to moisture and poor electrical resistance. When choosing yellow and blue ceramic capacitors, be sure to find a professional manufacturer. Such as production equipment; research and development strength to ensure the quality assurance of ceramic capacitors. Find a regular high-voltage ceramic capacitor manufacturer, the ceramic capacitor model is complete, the parameter information is complete, the manufacturer can also provide reasonable assistance.
