SMD1812P020TFA is listed in the Ptc Resettable Fuses range at ChipApex. The manufacturer field lists Littelfuse Inc.. Its product description is PTC RESET FUSE 30V 200MA 1812. Review the specifications below when checking this part for your BOM.
The SMD1812P020TFA is a surface-mount PolySwitch resettable fuse from the SMD-P series by Littelfuse. It features a hold current of 2 A and a trip current of 3.5 A, with a maximum voltage rating of 8 VDC. The device exhibits an initial resistance of 60 mOhms and can withstand a maximum fault current of 40 A. Designed for PCB mounting in the 1812 (4532 metric) package, it operates within a temperature range of -40°C to +85°C.
Verify component authenticity against official Littelfuse documentation. Confirm that the part number matches the specific SMD-P series designation. Check for RoHS compliance details as indicated in manufacturer records. Ensure storage conditions align with moisture sensitivity requirements before assembly.
Select this component when designing circuits requiring resettable protection for low-voltage applications up to 8 VDC. Consider the 2 A hold current and 60 mOhm resistance for power loss calculations. Evaluate the 1812 footprint constraints against available board space. Verify thermal performance within the specified operating temperature range.
This device belongs to the POLY-FUSE SMD-P series, designed for surface-mount technology integration. It serves as a solid-state alternative to traditional fuses, offering repeated use after fault clearance. The series supports various industrial and consumer applications requiring compact overcurrent protection solutions.
Public confirmed substitute part numbers are not available in the provided documentation.
