Safety Recognized MLCC

Usage of safety capacitors: X capacitor is the capacitor connected between the two lines of the power line (LN), generally using metal film capacitor; Y capacitor is connected between the two lines of the power line and the ground line (LE.NE) Capacitors usually appear in pairs. Due to the limitation of the leakage current, the Y capacitor value cannot be too large. Generally, the X capacitor is of uF level, and the Y capacitor is of nF level. Connect a capacitor between FireWire and Line 0 is X, and connect a capacitor between Firewire and Ground like Y.
