X capacitors are used to suppress electrical noise by reducing the input impedance of
the device incorporating the capacitor.
X capacitors are connected across the supply line where failure of the capacitor will
not result in personal exposure to electrical shock.
X2 capacitors are to be used in applications where the peak voltage is <1200V.
