RIVERSIDE, Calif., August 3, 2011 – Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced the availability of two new evaluation boards for RS-485-based applications. Using Bourns® TBU® High-Speed Protectors (HSPs), GDTs, TVS diodes and MOV products, the new boards were developed as a design resource that streamlines evaluating circuit protection on RS-485 serial device ports. To meet the required industry standards on RS-485 port interfaces, the new boards provide two different evaluation approaches. The Bourns RS-485EVALBOARD1 includes two Bourns® TBU® High-Speed Protectors (HSPs), two Bourns® fast-acting GDTs and two Bourns® TVS diodes. The Bourns RS-485EVALBOARD2 uses Bourns® TBU® High-Speed Protectors (HSPs), MOVs and TVS products.

“Bourns designed the evaluation boards to help developers more quickly and easily determine the circuit protection required for their applications that use RS-485 serial device ports,” said Ian Doyle, product line manager of semiconductor products at Bourns, Inc. “The evaluation boards demonstrate that with Bourns® TBU® HSP solutions, we are able to offer enhanced performance features over competing technologies in terms of increased surge and transient protection levels on RS-485 ports that also enable an entire circuit protection solution to fit into a smaller PCB area.”

Bourns’ RS-485 evaluation boards are offered through the company’s distribution sales partners, with inventory available immediately at Digi-Key, Farnell and Mouser. As a pricing example, the Bourns RS-485EVALBOARD2 is priced at $20.00 in 10 piece quantities.

For more information, Bourns has produced a demonstration video that explains the use and benefits of its RS-485 evaluation boards in assessing port protection performance: http://www.youtube.com/watch?feature=player_profi lepage&v=dvCscFwlM_w

Bourns Announces Industry’s First ECL Triggered

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.

About Bourns® TBU™ Technology
Bourns’ TBU™ High Speed Protector is the first new approach to electronics circuit protection in over a decade. This technology is designed to block a transient through a current disconnecting mechanism. Rather than a complex interstage coordination between two shunting components, the TBU™ device allows customers to protect circuit boards from both overvoltage and overcurrent surges. The TBU™ device protects electronic equipment within nanoseconds, essentially eliminating latency common in the circuit protection design, limiting let-through energy. The TBU™ device has virtually no capacitance or inductance, and therefore can be used in high bandwidth applications. It has a resistive characteristic which permits currents up to a certain level to pass unimpeded to the protected interface. In higher current situations, the TBU™ device switches to a high impedance state, protecting until the surge voltage dissipates or the short-circuit reseals. The TBU™ device offers full bi-directional operation which is inherently resettable.
