Bourns has announced its latest series of TBU (Transient Blocking Unit) circuit protection devices designed for high speed protection of communications ports. The new devices are claimed to be the industry’s first electronic current limiters (ECLs) designed to tolerate AC mains power contact without circuit damage. Designated the TBU DT-Series, the new circuit protection device family provides protection against faults caused by short circuits, AC power cross, induction and lightning surges.
Unlike high capacitance protectors the new devices are fast-reacting protectors that do not alter the signal performance of high speed communication ports. Target markets include Ethernet ports used in outdoor applications such as security systems, PV panels and service kiosks.
The TBU DT-Series includes eight models with continuous AC voltage ratings up to 425 Vrms and nominal trigger currents ranging from 150 mA to 750 mA. The new device family comes in a surface mount DFN package and is lead free and RoHS compliant. Product samples are available now. TBU-DT-065 and TBU-DT-085 are priced at $.69 each in 15K quantities.
