What is the difference between y capacitor and high voltage ceramic capacitor?

The y capacitor is a capacitor that is connected across the power line between the two lines and the ground (L-E, N-E), usually in pairs. Based on the limitation of leakage current, the value of y capacitor should not be too large. Generally, the X capacitor is uF grade, and the y capacitor is nF grade. The X capacitor suppresses differential mode interference and the y capacitor rejects common mode interference. For communication, safety certification is required. There is capacity on the product; voltage; safety certification mark. The high-voltage ceramic capacitor is made of ceramic as a dielectric, and a silver layer is sprayed on both sides of the ceramic substrate, and then fired into a plate by a low-temperature firing of a silver film. Its shape is mostly in the form of a sheet, but also has a shape of a tube or a circle. For DC, no safety certification is required. There is only capacity and voltage on the product.

The difference between y capacitor and high voltage ceramic capacitor is that the printing is different; the pitch is different; the thickness of the product is different, the withstand voltage test is different, and the safety certification requirements are different. y capacitors and high voltage ceramic capacitors have been widely used in various electronic products. The corresponding capacitor can be selected according to the product requirements. y capacitor and high voltage ceramic capacitor are the same as electronic components, the appearance is mostly round blue. y capacitor and high voltage ceramic capacitor are different in printing; foot distance is different; product thickness is different, pressure test is different and safety certification requirements different.
