FAQ
How to choose the rated voltage of the capacitor?
When the capacitor is working, the DC voltage on it should be less than the rated voltage.

The principles for selecting the rated voltage of safety capacitors are as follows:
1) At low voltage, the ratio of actual working voltage to rated voltage can be higher.
2) At high voltage, the ratio of actual working voltage to rated voltage can be lower.
3) When working in AC state or when the pulse AC component on DC is relatively larger, the ratio should be selected lower, and the ratio should be lower if the frequency is higher.
4) When high reliability is required, the ratio should be lower.
What is the step-down principle of safety capacitors?
The principle of safety capacitor step-down is to use the capacitive reactance generated by the capacitor at a certain AC signal frequency to limit the large working current, that is, the terminal load pulls down the output voltage after the current limit. Safety capacitors actually play a role in limiting current and dynamically distributing the voltage across the capacitor and the load.
