Bourns has expanded its line of circuit protection systems 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. 

The Bourns C650, C850 and P40 product families feature 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 high speed data buses enabling them to meet speed and bandwidth requirements for reliable power surge protection. The TBU devices also have a small footprint and meet high equipment uptime requirements in space-constrained applications such as avionics, defense and mass transit applications. 

Bourns' TBU products offer features required for circuit protection in industrial, test, security and process control equipment applications including speed, bandwidth and resettability. 

The devices are compatible with faster next-generation chipsets and are resettable within microseconds to provide immediate recovery in critical operations. The TBU devices meet application needs for linearity and high frequency applications to match the demands of high data rate equipment designs. 

The devices are optimized for 24/7 deployments where circuit protection needs to be immediate to maintain optimal operating functions.  Bourns' TBU technology is designed to immediately block a transient through a current disconnecting mechanism, offering superior protection. 

Pricing and availability

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.
