What happens after safety Y capacitor fails

Safety Y capacitors are produced and tested according to the international standard IEC 60384-14. 100% qualified shipment. Its main structure consists of tiles, electronic leads and epoxy resin. The ceramic media is made of ceramic powder, sintered at high temperature, then silver electrodes are coated on both sides, and then soldering leads and epoxy resin are applied.

If the safety Y capacitor is broken down on the PCB board. There are only two possibilities, one is thermal breakdown and the other is electrical breakdown. Either way, the capacitors that break down are all judged to be capacitor failures: they are non-conductive and do not have power. Because the internal chip structure has been destroyed, the edges are broken, and the two terminals are in a disconnected state. The appearance of the capacitor is generally not damaged, and the more serious situation is that the traces of breakdown of the encapsulated material on the surface of the safety capacitor are black. Therefore, after the failure of the safety Y capacitor, it will only be without electricity, it will not be a fire, and will not affect the safety of the user.

To ensure the safety of use. Pay attention to working voltage, working environment, and working time when using, and operate strictly in accordance with GB standard or IEC standard. It is recommended that the safety Y capacitor be used together with the X capacitor, with better withstand voltage and reinforced insulation. Safety Y capacitors are broken down on the PCB board. There are two possibilities. One is thermal breakdown, and the other is electrical breakdown. The performance is judged as failure of the capacitor is not conductive, no electricity, no fire, It will not affect the safety of users.
