Bourns Announces Its Lowest Resistance Battery Strap Resettable Fuse



New Miniature-Sized Battery Strap Resettable Fuse Offers an Initial Resistance of Just 5 to15 mOhms

RIVERSIDE, Calif., - 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 $0.25 each in 10K piece quantities.
