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.
