What is the Capacity of Y Capacitors?(I)

The main function of Y capacitor is to suppress EMI conduction interference. It is used to eliminate the common mode interference and the interference of the high frequency part above 1M. It is also the capacitor that straddles two lines of power line and the ground separately, usually appears in pairs. Y-capacitor grounding plays a filtering role. The capacitance of the limited Y capacitor based on leakage current should not be too large.

What capacity specifications do Y capacitors have? The capacity of Y capacitors ranges from 10PF to 10000PF. The voltage specifications are different, the corresponding characteristics are different, the error is also different, and the size of each part is also different. Please refer to the table below.
