Ceramic capacitors are used in 300V AC circuits

Usually the ceramic capacitors that our industry provides are only available in DC circuits. Regarding surge safety ceramic capacitors for 300 VAC circuits, although they have been produced, they require strict pulse and large instantaneous voltage checks that meet international standards, so the field of capacitance is subject to many restrictions.

For example, a capacitor with a rated voltage of DC is often used in an AC environment. The usual method is to use the DC capacitor to the bottom of the AC environment. This can only provide the required reliability, but it can not measure what kind of change the capacitor will produce under actual working conditions. Zhixu Electronics' 300VAC series ceramic capacitors are designed to ensure reliability and consistency in AC applications.

Another factor that needs to be considered is the self-heating effect of the capacitor, which is related to the capacitance value of the ceramic capacitor, the loss factor, the number of cycles, and the large value of the applied voltage.
