Ceramic capacitors are used in 300V ac circuits

In general, the standard of ceramic capacitance that our industry provides is limited to DC circuits. Although the surge safety gauge ceramic capacitors for 300VAC circuits have been produced, they need to undergo rigorous pulse and large instantaneous voltage checks to meet international standards, so the capacitance domain is subject to many restrictions.

Capacitors rated as DC, for example, are often used in ac applications. The usual method is to put the DC capacitor on the ground and use it in an alternating current environment. This can only provide the required reliability, but it cannot measure what changes the capacitor will make in the actual working condition. Zhixu electronics' 300VAC series ceramic capacitors are designed to ensure reliability and consistency in ac applications.

The other factor to consider is the self-heating effect of capacitors, which is related to the capacitance value, loss factor, cycle times and large value of applied voltage of ceramic capacitors.
