Ptc Resettable Fuses Procurement Notes

Verify the specific suffix DR indicates reel packaging when ordering. Confirm RoHS 3 compliance status matches current regulatory requirements. Ensure the 16V rating aligns with the target circuit's maximum operating voltage. Check for any recent PCN updates regarding material or manufacturing changes.

Ptc Resettable Fuses Selection Notes

Select this component based on the 1.1A hold current requirement for the protected circuit. Ensure the 16VDC maximum voltage rating exceeds the system's peak voltage. Consider the 1812 footprint constraints for PCB layout. Verify that the 100A maximum fault current capability is sufficient for the potential short-circuit conditions.

Ptc Resettable Fuses Part Context

This part belongs to the Littelfuse POLY-FUSE 1812L series, which offers various voltage and current ratings in a standardized 1812 SMD package.
