The Littelfuse 0805L075WR is a polymeric PTC (Positive Temperature Coefficient) resettable fuse designed for overcurrent protection in compact electronic circuits. It features a hold current of 750 mA and a trip current of 1.5 A at 20°C still air. The maximum voltage rating is 6 Vdc, and it can withstand up to 40 A of fault current. Power dissipation in the tripped state is typically 0.6 W. The device has a low initial resistance of 90 mΩ minimum, increasing to 350 mΩ maximum after tripping. The time to trip at 8 A is 200 ms.
This resettable fuse is housed in a surface mount 0805 (2012 Metric) concave package, with dimensions 2.10 mm x 1.35 mm and a maximum thickness of 0.75 mm. It operates over a temperature range of -40°C to 85°C. The 0805L series is RoHS compliant and offers resettable protection for applications where space is limited.
Typical applications include overcurrent protection in USB ports, battery packs, mobile devices, and other low-voltage power circuits. The polymeric PTC material automatically resets after the fault is cleared and power is removed, eliminating the need for fuse replacement.
