X,Y电容都是安规电容,火线零线间的是X电容,火线与地间的是Y电容.它们用在电源滤波器里,起到电源滤波作用,分别对共模,差模工扰起滤波作用.
安规电容是指用于这样的场合，即电容器失效后，不会导致电击，不危及人身安全.?
安规电容安全等级应用中允许的峰值脉冲电压过电压等级(X, Y capacitors are all safety regulation capacitors, and the X between the lines is X capacitors. The FireWire and the ground are the Y capacitors. They are used in the power filter and play the role of power filter, which plays the role of common mode and differential mode interference.
The capacitor is used for such occasions, the capacitor failure, will not cause electric shock, do not endanger the safety of.
Permissible peak pulse voltage overvoltage level in application of safety grade of safety gauge)
