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.
With its fast response characteristic and operating temperature capability up to 150°C, 440 series makes possible, even in ultra high operating temperature conditions, the AC/DC circuit of the electronic appliance well protected when over-current occurs.
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.
