What is the difference between ceramic capacitor and Y capacitor?(II)

    Y capacitors are general equipotential connected capacitors during the two and bottom lines of the power line, usually presented by pair. In view of the limitation of leakage current, the value of Y capacitor can not be too large, usually X capacitor is UF stage Y capacitor is n F stage. Y capacitors control common-mode noise interference. The discharge of Y capacitor is different from that of ordinary capacitor. Ordinary capacitor will keep the charged material for a period of time after the external power supply is disconnected. If you touch it by hand, it will be electrified, but the Y1 capacitor will not be in such doubt. In view of safety and EMC quotient, it is usually proposed to add an Anchorage Y capacitor to the power supply interface.


    The essence of ceramic capacitance and Y capacitor is that ceramic capacitor does not need safety certification and has good resistances, high voltage Y capacitor is anti-electric, and needs safety certification (important).
