The discharge of x2 safety capacitor is different from the ordinary capacitor, the ordinary capacitor will keep the charge for a long time after the external power supply is disconnected. x2 safety capacitor will be electrified if you touch it by hand, but the safety capacitor does not have this problem. In the AC power input, generally need to add 3 safety capacitors to suppress EMI conducted interference.
