RIVERSIDE, Calif., February 15, 2011 – Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced a new line of open LED shunt protection devices designed specifically for LED lighting applications. Designated the Bourns® LSP-Series, the new shunt protector family enables LED lighting applications configured in strings to be more robust and reliable. Most LED designs include solid-state lighting luminaries configured in series strings of 20 or more LEDs. In this configuration, an open LED can cause the entire LED string to go dark, resulting in reduced performance and possible maintenance calls and costly warranty returns. Adding a Bourns® LSP-Series shunt protector to an LED design allows the unaffected lights in the string to remain illuminated by shunting current around the inoperable LED. The new LSP-Series of open LED shunt protectors are an optimal solution for a variety of LED lighting applications including light bulbs, lighting fixtures and backlighting systems.

“LED lighting applications are exploding in volume,” said Ian Doyle, product line manager of semiconductor products at Bourns, Inc. “Bourns’ new LSP-Series of open LED shunt protectors address the failure rates of early LED designs. Incorporating a Bourns® LSP device into the design of LEDs improves reliability and helps eliminate costly downtime.”

The Bourns® LSP-Series of open LED shunt protectors include four models: LSP0600BJR-S, LSP0900BJR-S, LSP1300BJR-S and LSP1800BJR-S. Customers can maximize the level of protection by selecting Bourns® model LSP0600BJR-S and using one device per LED. Alternatively, customers can reduce their protection costs by selecting Bourns® models LSP0900BJR-S, LSP1300BJR-S or LSP1800BJR-S that are able to isolate groups of two, three or four LEDs respectively. Bourns’ new device family comes in an SMB surface mount package and is RoHS* compliant.  Product samples are available now through Bourns’ distribution partners. As a pricing example, Bourns® LSP0600BJR-S is priced at $.30 each in 10K piece quantities.

RIVERSIDE, Calif., April 27, 2011 — Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced the company’s smallest battery strap resettable fuse featuring ultra-low resistance designed to deliver reliable and robust circuit protection.  Designated the Bourns® Multifuse® MF-LL Series, the new battery strap resettable fuse was developed in response to  portable electronics industry demand for a miniature-sized, resettable overcurrent protection with the lowest possible resistance.  The new fuse meets the circuit protection requirements of rechargeable battery packs used in portable electronic devices such as mobile phones, MP3 players and digital cameras.

“Using its lowest resistance PTC formulation to date, Bourns has produced a resettable fuse from a chip of less than 11 mm².  Resettable fuses of such small size generally have quite high resistance values, but Bourns’ new MF-LL Series overcomes this limitation and offers an initial resistance of just 5 to 15 mOhms,” said Brian Ahearne, Multifuse® product line manager at Bourns, Inc.  “As the electronics industry continues to evolve at a rapid pace, the launch of the new MF-LL Series demonstrates Bourns’ ongoing commitment to next-generation resettable fuse development.”

The Bourns® MF-LL1190 Model is available now.  Future models in the series are in development and are scheduled for release in the second quarter of 2011.  The MF-LL Series is also RoHS* compliant.  As a pricing example, Bourns® MF-LL190 is priced at .25 each in 10K piece quantities.
