Bourns Announces Industry’s First ECL Triggered By Excessive Voltage or Current

Riverside, Calif., June 29, 2010 - Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced its latest series of Transient Blocking Unit (TBU™) circuit protection devices designed to protect telecommunications applications from surges in the industry’s first electronic current limiter triggered by excessive voltage or current. Designated the Bourns® TBU™ PL-Series SLIC, the new circuit protection device family provides extremely fast overcurrent protection combined with SLIC battery voltage tracking triggered protection. Combined with additional overvoltage protectors, this new solution protects against very high surge levels and meets telecom 500A Telcordia GR-1089 intrabuilding and 6kV/150A ITU-T standards.

Protecting sensitive telecom applications from the potentially damaging effects of surges that can cause current and voltage to rise above normal operating levels, the Bourns® TBU™ PL-Series responds in 100 nanoseconds. The resettable circuit protection devices also feature significantly lower let-thru energy and overshoot protection, which reduces stress on the SLIC and the printed circuit board (PCB) for increased reliability and product life. Bourns’ new TBU™ series also cuts the circuit protection component count to three devices compared to the seven needed in a conventional gated thyristor solution because there is no need for peripheral R-C or L-C components nor additional GDTs for increased surge requirements that take up valuable PCB space and increase manufacturing costs.

“Similarly, for customers who are currently using the Bourns® P-G TBU™ series, the new Bourns® TBU™ PL-Series drastically reduces the component count and the TBU™ package size is 25 percent smaller to better meet our customer’s needs for board area and height reductions,” said Paul Wiener, telecom market director at Bourns. “This new TBU™ series provides the best of both worlds – the highest protection levels with the fewest number of components.”

The Bourns® TBU™ PL-Series is available in three voltages (850, 600 and 500) and two operating current levels (100 mA and 200 mA) that match worldwide standards and SLIC chipset requirements. Product samples, evaluation boards and sample kits are available now through Bourns’ distribution partners. As a pricing example, Bourns® TBU-PL050-100-WH is priced at ($.056 each) in (3K) quantities.
