Operating up to 150°C, 440 Series has high inrush current withstand rating up to 12.95 A²s for eliminating nuisance fuse open during momentary overload conditions. Surface mount 1206-size units have max fault current rating of 50 A at rated voltage and are 100% lead-free, halide-free, and RoHS-compliant. Fuses are particularly suitable for protecting AC/DC over-current conditions in LCD TVs, LCD monitors, notebook computers, hard disk drives, and XDSL modems.
Littelfuse new 440 Series 1206-size High I2t Surface-Mount Ceramic Fuse Offers Superior Electrical Performance in High Working Ambient Temperature up to 150 °C
New fuse series provides ultra high inrush current withstand capability and is suitable for applications that experience high operating temperature environment.
CHICAGO, Illinois, September 28, 2009 - Littelfuse, Inc. (NASDAQ/NGS:LFUS), ) today introduced the 440 Series surface mount 1206-size high I2t surface mount fuse with excellent electrical stability and reliability.

The 440 series has the highest inrush current withstand (I2t) rating of up to 12.95A²s (8A current rating) for eliminating nuisance fuse open during momentary overload conditions. The series has a maximum fault current rating (Interrupt Rating) of 50A at the rated voltage and is 100% lead-free, halide-free and compliant to RoHS requirements.
The 440 Series has UL and CSA agency approvals and has a broad line of current ratings from 1.75A to 8A (32VAC/32VDC) to meet different application needs. Current ratings from 250mA to 1.5A will be introduced soon in the second phrase of the launch.
It is particularly designed for protecting AC/DC over-current conditions of a wide range of end device applications which are subject to high operating temperature including inverters of LCD TVs, LCD monitors, notebook computers, hard disk drives, XDSL modems, set-top boxes, Li-ion battery packs and gaming consoles.
