Y capacitor

The capacitance of the Y capacitor must be limited, so as to achieve the purpose of controlling the size of the leakage current flowing through it under the action of the rated frequency and rated voltage and the impact on the EMC performance of the system. GJB151 stipulates that the capacity of the Y capacitor should not be greater than 0.1uF. In addition to complying with the corresponding power grid voltage withstand voltage, the Y capacitor also requires sufficient safety margin in terms of electrical and mechanical properties to avoid breakdown and short circuit phenomenon under extremely harsh environmental conditions. Protecting personal safety is of great significance. It is particularly pointed out that the Y capacitor as a safety capacitor must be certified by a safety testing agency. The appearance of Y capacitors is mostly orange or blue, and they are generally marked with safety certification marks (such as UL, CSA, etc.) and withstand voltage AC250V or AC275V. However, its true DC withstand voltage is as high as 5000V or more. It must be emphasized that ordinary capacitors such as nominal withstand voltage AC250V or DC400V should not be used for Y capacitors at will.

structure

The specific details of the supercapacitor structure depend on the application and use of the supercapacitor. These materials may vary slightly due to manufacturer or specific application needs. Common to all supercapacitors is that they contain a positive electrode, a negative electrode, and a separator between the two electrodes, and the electrolyte fills the two pores separated by the two electrodes and the separator.
