Littelfuse Introduces Ultra-Small Surface-Mount PPTC Resettable Overcurrent Protection Device

New Polyfuse® PPTC series offers superior electrical performance and first
0603 size (.063" x .032") device of its type on the market

DES PLAINES, IL -June 3, 2008 - Littelfuse, Inc. the leader in circuit protection has introduced the 0603L series Polyfuse® PPTC (polymer positive temperature coefficient thermistor), a new micro form-factor resettable over-current protection device. Its extremely small size, excellent electrical ratings, and TUV and UL safety standard certification meet the need for reliable circuit-protection in ever-shrinking consumer electronic devices.

Continuing on the momentum in over-current protection miniaturization following the introduction of the popular 0805L Polyfuse PPTC series, the Littelfuse introduction of the 0603L series leads its category in supporting industry demands for ever-smaller electrical circuit components and end products.

The 0603L PPTC series is available in four hold current / maximum voltage ranges, including 0.10A/15Vdc, 0.20A/9Vdc, 0.25A/9Vdc and 0.35A/6Vdc.

Each device has a maximum fault current rating of 40A and is certified by both TUV and UL.

These devices can serve a wide range of end device applications including small consumer electronic products such as mobile phones and computers, Flash drives, USB thumb drives, hard disks, computer peripherals, and many others.

PPTCs are over-current protection devices that increase resistance as temperature increases due to increased current flow. They are designed to limit unsafe currents while allowing constant safe current levels. The resistance resets automatically when the current and temperature return to a safe level. PPTCs are typically used in sensitive applications where frequent over-current conditions occur or where constant system uptime is required.

With the world's broadest range of fuses and PPTC devices, Littelfuse is able to offer design engineers the most over-current protection options from a single supplier, along with the widest range of other circuit protection technologies and support.

Littelfuse Polyfuse 0603L PPTCs are now available for order and sample requests through most authorized Littelfuse distributors worldwide. For a listing of Littelfuse distributors, please visit www.littelfuse.com.
