Recently, Vishay Intertechnology, Inc. (NYSE stock code: VSH) announced the launch of a new series of axial cement wirewound resistors, the Z300-C series, the industry's first device with 12kV custom high voltage surge withstand capability.
Vishay Draloric devices are designed to limit inrush current during high voltage surges and are suitable for use in power supplies in electrical, industrial and household appliances and electronic ballasts. To improve safety under overload conditions, these devices feature a non-combustible cement coating and a high grade ceramic core.
The Z300-C series can withstand high voltage surges of 12kV and meets the requirements of IEC 61000-4-5 (1.2μs/50μs). The maximum allowable surge handling capability depends on the resistance model and the ohmic value.
At an ambient temperature of 40 ° C, the power rating of the resistor is 1 W to 6 W, and at 70 ° C it is 0.9 W to 5.4 W. The resistance of the device is 0.15~10k?, other resistance values ​​can be provided according to user requirements. The resistance tolerance is ±5% and ±10%, and the temperature coefficient is ±200ppm/K (the resistance is less than 1? is ±400ppm/K). ).
The Z300-C is compliant with the RoHS and Vishay green standards.
