Mouser Electronics is stocking the Bourns’ Transient Blocking Units circuit protection devices.
       
The Bourns TBU series provides an effective barrier by blocking a transient through a current disconnecting mechanism, rather than diverting or shunting the surge to ground.

The TBUs are high speed surge protection designed to protect against short circuits, AC power cross, induction, and lightning surges.

Bourns TBU products are resettable for full functionality after multiple fault events, offer a high bandwidth of 3 GHz, and are designed for telecommunication, industrial, and data communications systems.
       
Bourns has created four diverse TBUs with wide ranging impulse and RMS voltages, trigger current levels, and footprints. The P40 series was designed for VDSL protection, the P-G series for voice protection, the C series for general electronics protection, and the P-U series for Ethernet protection.
