440 Series High I²t 1206-Size Ceramic SMD Fuses

The Littelfuse 440 series offers superior electrical performance in high-working ambient temperatures.

Image of Littelfuse's 440 Series 1206 High I²t Ceramic SMD FusesThe Littelfuse 440 Series is a 100% lead-free, RoHS compliant and halogen-free fuse series designed specifically to provide over-current protection to circuits that operate under high working ambient temperatures up to 150°C and high inrush currents.

The 440 Series has the ultra-high I²t ratings of up to 12.95 A²Sec for eliminating nuisance fuse openings during momentary overload conditions. The series has a maximum fault current rating of 50 A at the rated voltage and is 100% lead-free, halide-free and compliant to RoHS requirements.

Features Applications
  • Operating temperature from -55°C to +150°C
  • 100% lead-free and RoHS compliant
