Ptc Resettable Fuses Procurement Notes

Verify that the specific suffix X1001 aligns with the required packaging quantity and reel specifications for automated assembly processes. Confirm that the 60V DC rating and 6.0A hold current meet the target circuit requirements. Ensure compliance with RoHS standards and check for any specific agency approvals required by the end application regulations before finalizing procurement orders.

Ptc Resettable Fuses Selection Notes

Select this component when a 6.0A hold current and 60V DC maximum voltage are required for radial through-hole applications. Consider the 85°C maximum operating temperature limit for thermal management design. Evaluate the 30 milliohm maximum resistance to ensure it does not cause excessive voltage drop in the target circuit during normal operation.

Ptc Resettable Fuses Part Context

This part belongs to the Littelfuse 30R series of polymeric positive temperature coefficient (PPTC) resettable fuses. The series is characterized by its compact rectangular package and radial leads, suitable for space-constrained PCB layouts. It serves as a reusable alternative to traditional one-time fuses in low-voltage DC circuits.

Ptc Resettable Fuses Replacement Considerations

Publicly confirmed substitute part numbers for the 30R600UMRX1001 are not available in the provided documentation. Verify compatibility with generic 6.0A/60V radial PTC fuses only if official cross-reference data is obtained from the manufacturer.
