【选型】小体积大通流量,硕凯放电管SC1812-300CSMD PTP 兼容4532-301-LF
众所周知,陶瓷气体放电管,是防雷设备中,应用最常见的一种开关电路保护器件,是一种由陶瓷材料制成的特殊结构的气体放电设备,在其放电间隙之间充填某种特性的惰性气体充当介质,并配置活性很高的电子发射材料,在高温环境下进行焊接构件的。
在数据通信设备雷击浪涌的保护应用方面,市场上有选用君耀电子的气体放电管4532-301-LF进行设计,不过因供货周期和价格压力,很多客户会选择一款低成本、供货周期好的替代方案。本文重点推荐硕凯电子的SC1812-300CSMD可pin-pin兼容君耀电子的4532-301-LF,典型电性参数对比参考如下图1所示。
