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
