The value of the Y capacitor in the small appliance

The Y capacitor in the small appliance is one of the indispensable capacitors. The Y capacitor is used for common mode filtering. It is connected between L or ground and N, and filters out the common mode signal of L to ground or N to ground. Y Capacitors are usually used symmetrically, and the functions are mainly bypass; decoupling; filtering; energy storage. How to calculate the value of the Y capacitor in the small appliance, look down together.

The Y capacitor is divided into Y1, Y2, Y3, Y4;

1. The rated voltage of Y1 is ≤500VAC, the peak voltage is equal to 8 kV, and the experimental voltage is 4000VAC.

2. The rated voltage of Y2 is ≥150VAC, ≤500VAC, the peak voltage is equal to 5 kV, and the experimental voltage is 1500VAC.

3, Y3 high pressure n / a, has been replaced.

4. Y4 withstand voltage is greater than 2.5 kV.

In the household air conditioner, the Y capacitor in the filter circuit can be selected according to the power of the switching power supply and the size of the load. It can also be calculated according to the formula =L/2π*C. Purchase safety capacitors and remember to find a guarantee to avoid unnecessary trouble.
