Y capacitors in safety capacitors: The two Y capacitors are connected in a critical position and must meet the relevant safety standards in order to prevent electronic devices from leakage or case charging, which can easily endanger personal safety and life. They are safety capacitors, which require the capacitance value not to be large, and the withstand voltage must be high. Therefore, the total capacity of Y capacitor should not exceed 4700PF (472).
GJB151 stipulates that the capacity of Y capacitor should be no more than 0.1uF. In addition to conforming to the corresponding grid voltage withstand voltage, Y capacitors are required to have sufficient safety margin in electrical and mechanical performance to avoid The voltage withstand performance of Y capacitor is important to protect personal safety.　Y capacitors are mostly orange or blue in appearance, and are generally marked with safety certification marks (such as UL, CSA, etc.) and withstand voltage of AC250V or AC275V. However, the real DC withstand voltage is up to 5000V or more. It must be emphasized that Y capacitors should not be used as a substitute for ordinary capacitors with nominal withstand voltage of AC250V or DC400V.
