从技术上讲,电子保险丝是一种集成电路,可为电路和电子元件提供过流、过压、过热和励磁涌流保护。电子保险丝还具有限流特性,可以实时向自动开关和用户传输诊断数据。电子保险丝内置的热和过压关断器件可防止故障对下游造成损坏。电子保险丝专为安装在印刷电路板表面而设计,可用于网络服务器、数据存储设备、扩展坞、平板电脑和计算机冷却风扇驱动器中。
  • 输入电压范围很宽,从2.7 V dc到24 V dc
  • 最大输入和输出电压为30 V dc
  • 提供 3 引脚、8 引脚、10 引脚或 16 引脚
  • 获得无铅且符合RoHS标准的认证
  • 小尺寸设计(例如2.9x2.9x0.7毫米)可节省PCB空间
  • 内部软启动开关的低导通电阻可最大限度地减少启动期间的功率损耗和电流冲击
  • 外部可编程限流特性、过压阈值和软启动时间
  • 可选故障指示器
