SMD030F-2 Description

Short technical summary and product information.

The Littelfuse PolySwitch SMD030F-2 is a polymeric PTC resettable fuse designed for overcurrent protection in space-constrained applications. It offers a hold current of 300 mA at 20°C still air and a trip current of 600 mA. The device can withstand a maximum voltage of 60 V and a maximum fault current of 10 A.

 

In the tripped state, the SMD030F-2 dissipates 1.7 W of power. Its minimum resistance is 1.2 Ω, and the maximum resistance one hour after tripping or reflow is 4.8 Ω. The time to trip at 1.5 A is a maximum of 3 seconds.

 

This component is housed in a 2920 surface mount package (2-SMD) with dimensions of 7.36 mm length, 5.12 mm width, and 3.18 mm maximum thickness. It operates over a temperature range of -40°C to 85°C. The SMD030F-2 is RoHS compliant, lead-free, and halogen-free.
