The Littelfuse MICROSMD005F-2 is a polymeric PTC resettable fuse designed for overcurrent protection in low-power circuits. It features a maximum voltage rating of 30V and a hold current of 50mA, with a maximum post-trip resistance of 50Ω. The device trips in 1.5 seconds under fault conditions, resetting automatically once power is removed and the fault clears.
This surface mount fuse is housed in a compact 1210 (3225 Metric) concave package, measuring 3.22mm x 2.58mm x 0.85mm. It operates over a temperature range of -40°C to 85°C, making it suitable for a variety of environments. The polymeric construction ensures fast response and robust performance in repetitive fault conditions.
Typical applications include overcurrent protection in USB ports, battery packs, and other portable electronics where resettable protection is required to prevent damage from short circuits or overload events.
