【应用】力特125V/5A特快熔型保险丝用于5G模组电源输入过流防护,有助于小型化设计
5G模组一般需要多种不同规格的电源模块供电,为避免5G模组电源输入因后级短路异常出现可燃风险,建议在电源输入母线上加入快熔保险丝做过流保护设计,考虑到电源输入电压范围一般为5~75V,可选择常规125V耐压的保险丝,同时,而额定输入电流一般在2.5A左右,选择额定工作电流为4A的保险丝即可;
针对如上的设计需求,推荐选择LITTELFUSE(力特)特快熔型保险丝0453004.MR,额定电压为125VAC/VDC,额定电流为4A,推荐理由如下:
1、 常温25℃条件下的正常冷却阻值为16mΩ,自损耗很小;
2、 工作温度范围-55℃~125℃,适用于极端低温环境工作;
3、 采用表面贴装设计,典型封装尺寸6.1x2.69mm,可节省PCB占板空间;
4、具有出色的快速的响应能力,在2倍过流的情况下,最大熔断时间仅5s,相关过流特性参数可参考如下图1所示。

5、具有良好的供货交期,可以快速支持样品和量产服务。
