The selection of EMC protection devices for data center switches must meet safety certification requirements: The power port varistor must be UL1449 certified, such as the Yinte Electronics 14D561K which has UL/cUL certification; the Y capacitor must meet IEC60384-14 safety capacitor certification; the gas discharge tube must be UL497B certified; and the TVS must meet AEC-Q101 or IEC61000-4-5 surge life test requirements. During the design phase, it is necessary to verify that: the maximum continuous voltage of the varistor is ≥1.2 times the rated voltage; the leakage current of the Y capacitor is <0.75mA; and the fuse breaking capacity is higher than the expected short-circuit current. Providing a complete set of safety compliance certificates is a service commitment of Yinte Electronics.
