The Littelfuse SMD185F-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 33V and a hold current of 1.85A, with an initial minimum resistance of 165 mOhm. The device trips within 5 seconds under fault conditions, providing reliable circuit protection.
This PTC fuse is housed in a compact 2-SMD surface-mount package measuring 8.70mm x 6.36mm with a maximum thickness of 3.00mm. It is suitable for automated assembly and is designed for operating temperatures ranging from -40°C to 85°C.
Typical applications include overcurrent protection in power supplies, battery packs, and consumer electronics where resettable protection is preferred over one-time fuses. The polymeric construction allows the device to reset after the fault is cleared and power is removed.
