PLED 单向系列开路 LED 保护器
Littelfuse PLED 单向系列（PLEDxUx 系列）开路 LED 保护器可在某个 LED 发生开路故障时提供一个转换电子分路，这样可确保即使灯串中的某个 LED 发生开路故障，其他 LED 仍可以正常工作。该系列保护器还提供了反向电池或反向电源极性保护。PLED 单向系列器件可为街道照明、户外广告牌、飞机跑道照明、路旁警示灯等户外 LED 照明应用提供高可靠性。该系列器件与具有 3V 标称正向压降特性的 1W、2W、3W LED 兼容，提供了 DO-214AA 和四方扁平无引脚 (QFN) 两种封装形式。QFN 的低外形和芯片级封装特性非常适合密集电路板应用。 了解更多
PLED Open LED Protectors
Littelfuse PLED Open LED Protectors provide a switching electronic shunt path when an LED in an LED array fails as an open circuit, ensuring the entire array of LEDs will continue to function even if a single LED in the array does not. These LED protection devices are compatible with 1W, 2W, and 3W LEDs that have a nominal 3V forward characteristic. The protectors are available in a variety of package types, including QFN and DO-214 surface-mount packages, SOT-89, and the small form factor Powermite® package. Littelfuse PLED Open LED Protectors offer reliable lighting functions in applications such as headlights, aircraft, aircraft runway lighting, roadside warning lights, and more.
