Do Y capacitors be used in pairs?

Everyone knows that the successful operation of the board is composed of several different types of capacitors. Some people ask whether the Y capacitors should be used in pairs. In fact, this depends on the actual situation on the board. The board can be run with a Y capacitor, and some require a few, and the capacity requirements are different.

The Y capacitor has an EMI effect. Generally, we will see that the two Y capacitors are used in series to increase the withstand voltage, and the purpose of increasing the Y capacitor is to over-EMI. When using it, there are national safety standards. You can learn about this knowledge. If you don't know it, you can consult the technical staff to make sure that it is used correctly!

Different standards have different requirements. Specifically, we still need to use Y capacitors in combination with our own situation. If you have technical questions, please contact us and we will try our best to solve the problem for you.
