Safety specifications

It includes two types of X-capacitors and Y-capacitors. The x-capacitor is a capacitor that is connected across two lines (LN) of the power line. Generally, a metal film capacitor is used; the Y-capacitor is connected across two lines of the power line and the ground (LE) respectively. The capacitance of NE) is generally paired. Based on the limitation of leakage current, the value of Y capacitance cannot be too large. Generally, X capacitance is uF level and Y capacitance is nF level. X capacitance suppresses differential mode interference and Y capacitance suppresses common mode interference.

X capacitor refers to the metallized film material safety capacitor, divided into X1, X2, X3 series, according to the material is divided into two specifications: MPX polypropylene material and MEX polyester material. The Y capacitor is a ceramic capacitor and is divided into two series of Y1 and Y2.

The following describes the specifications of the safety capacitor, which are the specifications of the X2 capacitor and Y capacitor.

There are many safety capacitor specifications. The X and Y capacitors in the safety series have different specifications and voltages. The corresponding sizes are different. In the selection process, according to the product's power supply to the product voltage, select the product's detection parameters.
