Difference Between Voltage Withstand Value and Rated Voltage Value of Y Capacitor

The rated voltage of capacitor means that it can work safely under this voltage for a long time, and the voltage refers working voltage, that is to say, the capacitor has a certain desire to work with the voltage it can withstand, so as to ensure the normal operation of the capacitor. The rated voltage is the standard voltage to ensure the long-term stability of the capacitor. The applied voltage at both ends of the capacitor in use should not exceed this value. It is best to be equal to this value.

The Voltage Withstand Value is the maximum voltage the capacitor can withstand without breakdown, beyond which the capacitor will explode.  Voltage Withstand Value is generally only achieved when testing, used to test the quality of capacitors. Even in testing, the  Voltage Withstand Value is maintained for a short period of time. If the voltage test is carried out for a long time, the capacitor will be damaged. The voltage resistance of the capacitor must be higher than the rated working voltage. The voltage withstand value and rated voltage of the capacitor are different from each other.

The rated voltage of Y capacitor is the voltage suggested working voltage, the voltage value of capacitor must be higher than the rated working voltage. The rated voltage value of Y1 capacitor is 400V AC Y2 capacitor voltage value is 300VAC. The Y capacitor voltage is the maximum voltage the capacitor can withstand without breakdown.  Voltage Withstand Value is generally only achieved when testing, used to test the quality of capacitors. Even in testing, the Voltage Withstand Value is maintained for a short period of time. The Voltage Withstand Value of Y1 capacitor in Y capacitor is 4 000 V AC Y2 capacitor and the  Voltage Withstand Value of Y2 capacitor is 1800-2600VAC.
