Description 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 ### note Maximum voltage shown is peak impulse voltage withstand with a duration of no more than 10ms. ### Recognized UL E315805 Surface Mount Technology (Fuse) Surface Mount Technology * * Resettable Fuse * * is used to prevent damage to electrical and electronic circuits caused by excessive current. They can quickly switch from a low impedance state to a very high impedance state under electrical overload or short circuit conditions, and can automatically reset and return to a low impedance state after the fault disappears and the power is cut off. After thousands of cycles of use, it is still a maintenance free automatic reset small model that does not require a fuse holder. It is mainly used for safety system power supply and transformer power switch devices, automotive and medical equipment instruments and control computers and peripheral devices, audio and video, and telecommunications

Bourns TBU 高速电路保护器,DT 系列 TBU - DT 的 Bourns TBU 系列是低电容双单向高速浪涌保护器,设计用于 防护短路、电感、雷电浪涌和交流电源相交所造成的故障。当一个方向的电流达到最大值时,这些 TBU 电路保护器将在 1μs 内跳闸。 该 TBU DT 系列电路保护器可阻止电压或电流的突然浪涌,并提供屏障,其后的电子就不会被损坏。 浪涌之后,当通过 TBU 设备的电压降至复位电压水平时,TBU 设备将复位。 典型应用包括以太网端口、保护模块、保护锁和过程控制设备。 高级电路保护 过电流和过电压保护 块浪涌高达额定限制 高速性能 小型 SMT 封装 工作温度范围:-40°C → +85°C ### 注 所示的最高电压为在不超过 10ms 的持续时间内耐受的峰值脉冲电压。 ### 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
