X2 Safety Capacitor.pdf
Safety X2 capacitors are a type of safety capacitors. Safety
capacitors are used in such occasions, that is, after the capacitor
fails, it will not cause electric shock and will not endanger
personal safety.
1. The main structure of the X2 safety capacitor.
It is made of metallized polypropylene film non-inductive structure
winding, using tinned copper clad steel wire, plastic shell and
flame retardant epoxy resin package.
Polypropylene film is used as the dielectric, and the zinc-aluminum
metal layer on the surface is vacuum-evaporated as the electrode.
It is manufactured by winding and other processes. The exterior is
packaged with (PBT) flame-retardant plastic shell and potted with
epoxy resin. The appearance design is compact and suitable for high
density occasion installation.
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.
