SMD050F-2 Description

Short technical summary and product information.

The SMD050F-2 is a polymeric PTC resettable fuse from Littelfuse Inc. It is designed for overcurrent protection in electronic circuits, automatically resetting after the fault is cleared. The device is rated for a maximum voltage of 60V and a hold current of 500mA, with a trip time of 4 seconds at specified conditions.

 

The initial resistance is 1.4Ω, and the operating temperature range spans -40°C to 85°C, making it suitable for a wide variety of environments. The fuse is housed in a 2-SMD surface mount package with dimensions of 7.36mm x 5.12mm x 3.18mm, allowing for compact PCB designs.

 

Typical applications include overcurrent protection in power supplies, battery charging circuits, and telecommunications equipment. The polymeric PTC technology provides reliable, resettable protection without the need for replacement after a fault event.
