Protection units

Bourns has released a range of transient blocking unit (TBU) circuit protection products.

It is designed to block a transient through a current disconnecting mechanism rather than diverting or shunting the surge to ground.

This virtually eliminates latency, which results in surge protection within nanoseconds. The devices provide wide bandwidth circuit protection against lightning, power induction, power cross and short circuit events in a wide variety of ethernet, (VoIP), very high-speed DSL (VDSL) and gigabit passive optical networking (GPON) applications.

There are four product families: the P-G series for voice protection, P40 for VDSL protection, the P-U series for ethernet protection and the C series for general electronics protection.

The P-G series meets high surge requirements and prevents arcing and other damage. Offering high bandwidth for VDSL and VDSL2 applications, the P40 TBU products meet rate-reach requirements.

The P-U is designed specifically for ethernet applications by protecting against both lightning and power cross events.
