The Littelfuse SMD250F-2 is a polymeric positive temperature coefficient (PTC) resettable fuse designed for overcurrent protection in electronic circuits. It is rated for a maximum voltage of 15V DC and a hold current of 2.5A. The device has a typical resistance of 85 mΩ and a trip time of 25 seconds at rated conditions.
This resettable fuse is housed in a compact 2-SMD surface mount package measuring 8.70mm in length, 6.36mm in width, and 3.00mm in thickness. It operates over a temperature range of -40°C to 85°C, making it suitable for a wide variety of environments.
Polymeric PTC fuses are commonly used in applications where overcurrent protection is required and where replacing a traditional fuse is impractical. The SMD250F-2 automatically resets after the fault is cleared and power is removed, reducing maintenance and downtime.
