X2 capacitor function

1. Suppress electromagnetic interference of power supply.

The most common function of the X2 safety capacitor is to suppress the electromagnetic interference of the power supply. It is generally placed at the entrance of the neutral wire and the live wire of the power supply. In the power supply, it is usually used together with the safety Y capacitor. The x-capacitor is a capacitor connected across the two wires (L-N) of the power line to suppress common-mode interference. Y capacitors are capacitors that are connected between the two lines of the power line and the ground (L-E, N-E), and generally appear in pairs to suppress differential film interference. If safety capacitors are not used in the power supply, EMC problems will occur when the power supply is certified, so safety capacitors are indispensable.

2. Resistor-capacitance step-down effect.

In addition to suppressing the electromagnetic interference of the power supply, X2 can also be connected in series in the circuit with a 100~250VAC power supply and used as a RC step-down capacitor. The resistance-capacitance step-down circuit is relatively simple and economical, and is often used in some low-power circuits, such as LED modules and small home appliance control.
