安全規制型コンデンサは、コンデンサが故障しても感電に至らず、生命の安全を脅かさないような場面で使用される。
There are many main occasions for the application of safety-regulated capacitors, mainly: resistive buck circuit, EMI filtering two.
Capacitance drop circuit is to use the capacitance generated by the safety capacitor in a certain AC signal frequency to limit the larger working current.
EMI filter is the main role is to filter out the external power grid of high-frequency pulses on the power supply interference, but also play a role in reducing the switching power supply itself electromagnetic interference.

The general EMI filter has two sets of capacitors, namely, cross-border in the power line between the differential mode suppression role of the X capacitor and connected to the power line and ground between the common mode suppression role of the Y capacitor. For the X capacitor and its rated voltage and grid voltage equivalent, its capacity can be selected for a larger, typical value of 0.05µF ~ 1µF. For the Y capacitor value allowed the larger the better, but if the Y capacitor failure will lead to electric shock, so there is a limit to its larger leakage current current.
