0805L050WR Description

Short technical summary and product information.

The Littelfuse 0805L050WR is a polymeric PTC resettable fuse from the 0805L Series, designed for surface-mount overcurrent protection in space-constrained applications. It offers a hold current of 500 mA at 20°C still air and a trip current of 1 A. The device can withstand a maximum voltage of 6 V and a maximum fault current of 100 A.

 

Typical power dissipation in the tripped state is 0.5 W. The maximum time to trip at 8 A is 100 ms. Initial minimum resistance is 150 mΩ, and maximum resistance one hour after tripping or reflow soldering is 850 mΩ.

 

The component is packaged in an 0805 (2012 Metric) concave case with surface-mount terminals. It is RoHS compliant, halogen-free, and lead-free per the datasheet. The operating temperature range is -40°C to 85°C. The device is rated AEC-Q200, indicating suitability for automotive applications.
