Bourns TBU High Speed Circuit Protector, KE Series The TBU-KE series of Bourns TBU are low capacitance unidirectional high speed surge protectors designed to protect against faults caused by short circuits, induction and lightning surges and AC power cross.These TBU circuit protectors will trip in less than 1 μs when the current reaches the maximum value in one direction. The TBU KE series circuit protector blocks sudden surges in voltage or current and provides a barrier behind which electronics will not be exposed to damage. Post surge, the TBU device resets when the voltage across the TBU device falls to the Vreset level. Typical applications include Ethernet ports, protection modules, dongles and process control equipment. Superior circuit protection Overcurrent and overvoltage protection Blocks surges up to rated limits High speed performance Small SMT package Operating temperature range -40°C → +85°C ### 注 Maximum voltage shown is peak impulse voltage withstand with a duration of no more than 10ms. ### 认可 UL E315805 ### 表面安装技术（熔丝） ### 表面安装技术 **可重置熔丝**用于防止电气和电子电路受到过度电流的损害。 它们可在电气过载或短路条件下快速地从低阻抗状态切换到极高阻抗状态，并可在故障消失和切断电源后自动重置并返回低阻抗状态。 使用数千个周期后仍是免维护自动重置 小型号，无需熔丝架 ### 主要应用 安全系统 电源和变压器 电源开关器件 汽车和医疗设备 仪器仪表和控制 计算机和外围设备 音频视频和电讯
