Procurement Notes
Verify component authenticity by cross-referencing the manufacturer part number with official Littelfuse documentation. Confirm that the specific suffix matches the required electrical ratings and package dimensions. Ensure compliance with RoHS directives and moisture sensitivity levels before integration into production workflows.
Selection Notes
Select this component based on the 100 mA hold current requirement and 30 VDC maximum voltage constraint. Evaluate the 6 Ohm resistance against power dissipation limits in the target circuit. Consider the 1812 footprint availability and thermal operating range when designing the PCB layout for optimal performance.
Part Context
This part is a member of the miniSMD family of resettable fuses from Littelfuse. It utilizes PolySwitch technology to provide reliable overcurrent protection in compact spaces. The series is widely used in applications requiring robust circuit protection with minimal board space consumption.
Replacement Considerations
Compatible substitutes include NANOSMDC100F-2 and MINISMDC075F/33-2. Verify that alternative parts meet or exceed the original voltage, current, and resistance specifications before implementation.
