A regular computer power supply manufacturer must have a rectifier bridge, a main control module, a main capacitor, a transformer, various MOS tubes, etc. Among them, the EMI module contains X capacitors and Y capacitors. Why are there safety regulations X and Y on the power supply? What about capac

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 fe

In fact, there are many kinds of capacitors, edit the introduction of several of our commonly used capacitors, may wish to follow the editor to see it! Capacitors are divided into two types: non-polar variable capacitors, non-polar fixed capacitors, and polar capacitors.From the material can be divi

Home televisions or electronic devices containing circuit boards contain a pair of Y capacitors, or even pairs of Y capacitors. Do you know which capacitors on these boards are Y capacitors? Today's editor comes to share with you the identification method of the Y capacitor. 1 Since the volume of th

The Y capacitor is one of the safety capacitors and the importance of the role in the circuit cannot be ignored. It can be said that if the Y capacitor does not exist, then there is no safety performance at all. The capacitor connected between the live line and the ground line and between the neutra

3. Data detection. The key test data of Y capacitor usually include electrostatic capacity detection, loss angle detection, insulation resistance detection, voltage strength detection. From these parameters, we can infer the quality of Y capacitor. 4. Timely inspection of manufacturers. Usually the

Y capacitor is the type of Safety capacitor, which means to use such a place, that is, after the capacitor fails, it will not cause electric shock, do not endanger the safety of human beings. What ways do we find Y capacitor problems and even circumvent problems? 1. Examination of appearance. After

Appearance of Y capacitor is mostly blue, generally marked with the safety certification sign (such as ULVDEEN CQCU KC logo) and voltage AC300V or AC400V words. However, its real DC withstand voltage is as high as 4000V. It must be emphasized that Y capacitors are not allowed to be replaced by ordin

The main function of Y capacitor is to suppress EMI conduction interference. It is used to eliminate the common mode interference and the interference of the high frequency part above 1M. It is also the capacitor that straddles two lines of power line and the ground separately, usually appears in pa

1. Examination of appearance. After getting the sample, check whether the powder coating on the appearance of Y capacitor product is average, whether the appearance is complete, whether the product parameter print and the safety gauge certification mark have any unclear place. 2. View the correspond
