Bourns, Inc. announced an expanded its line of circuit protection solutions for industrial applications to include Transient Blocking Unit (TBU) devices.  The TBU devices are designed for a broad range of applications including models for industrial, test, security and process control equipment.  Designated Bourns C650, C850 and P40 product families, the TBU models feature extremely low energy let-thru and are resettable to provide secure protection for a varying range of power surge threats from lightning and power cross to technician error and factory floor mishaps.  Bourns' TBU devices are compatible with very high speed data buses enabling them to meet speed and bandwidth requirements for reliable power surge protection.  The TBU devices also have a very small footprint and meet extremely high equipment uptime requirements in space-constrained applications such as avionics, defense and mass transit applications.

Bourns' C650, C850 and P40 TBU protectors are available now.  As a pricing reference, the C Series products are priced at $0.60 each in 5,000 piece quantities
