Bourns Announces
Breakthrough Transient Blocking Unit (TBU®)
|
Bourns' new TBU®
devices provide extremely effective, wide bandwidth circuit protection against lightning, power induction, power cross, and short circuit events in a wide variety of Ethernet, Voice over IP (VoIP), Very High Speed DSL (VDSL), and Gigabit Passive Optical Networking (GPON) applications. The TBU product is also used by customers in industrial, test, and measurement, sensors, and transportation applications.
All
Bourns TBU®
products are resettable for full functionality after multiple fault events and offer a high bandwidth of 3 gigahertz (GHz). While
Bourns' new
TBU
line exceeds system circuit protection requirements, the products are also a cost-effective solution that reduces warranty returns. TBU technology blocks transients through a current disconnecting mechanism rather than diverting or shunting the surge to ground. This virtually eliminates latency which enables surge protection within nanoseconds.
