The Littelfuse SMD300F-2 is a polymeric PTC resettable fuse designed for overcurrent protection in low-voltage circuits. It features a maximum voltage rating of 6V and a hold current of 3A, with an initial resistance of 48 mΩ. The device trips in 35 seconds under fault conditions, providing reliable circuit protection.
This component is housed in a compact 2-SMD surface mount package measuring 7.36mm x 5.12mm with a maximum thickness of 3.00mm. It operates over a temperature range of -40°C to 85°C, making it suitable for a variety of environments.
As a resettable fuse, the SMD300F-2 automatically resets after the fault is cleared and power is removed, eliminating the need for replacement. It is commonly used in applications requiring compact overcurrent protection where space is limited.
