英语翻译
PPTCs employ a low resistance conductive polymer that undergoes a phase change in electrical
characteristics when its temperature increases(i.e.,under higher current loads).When the temperature is reduced,it reverts to its low resistance state.As such,PPTCs work much like a conventional fuse,except that they can reset themselves automatically once an overcurrent situation is corrected.then Smart Power—the industry has been transformed.As a consequence,R&D activity by developers of all technologies increased dramatically.
PPTCs使用低阻抗的导电聚合物.温度上升时(也就是高的电流负荷),这种聚合物的电气特性会经历相变.而当温度降低时,它又会恢复到低阻抗状态.同样,PPTCs的工作原理类似传统的熔丝,只是前者能在过载电流状态被修正时自动重置.Smart Power改变了整个工业(这句不是很理解).结果,开发者针对科技的研发活动显著增多.
