Capacitors for suppressing power supply electromagnetic interference: When capacitors are used in power
supply cross-line circuits to eliminate noise, not only normal voltages, but also abnormal pulse voltages
(such as lightning) must be considered, which may cause capacitors to smoke Or catch fire. Therefore,
the safety standards of cross-line capacitors have strict regulations in different countries, so safety-certified
capacitors must be used.
It is not allowed to use DC capacitors as cross-line capacitors
At the same time, it is not allowed to use DC capacitors as cross-line capacitors. The X2 type capacitor for
suppressing electromagnetic interference of power supply should be suitable for occasions that will not
cause electric shock when the capacitor fails, such as the power supply is connected across the line, and
can withstand 2.5kV pulse voltage.
what is safe voltage
Safety capacitors refer to safety capacitors that will not cause electric shock or endanger personal safety after
the capacitor fails. Safety capacitors are usually only used for filtering in anti-interference circuits. They are used
in the power supply filter to filter the power supply, and filter the common mode and differential mode interference
respectively. For safety and EMC considerations, it is generally recommended to add safety capacitors to the power inlet.
