Ptc Resettable Fuses Procurement Notes

Verify the specific voltage rating configuration against application requirements, as datasheet references indicate variations between 16V and 30V ratings within the FSMD035 family. Confirm the manufacturer source is RFE or Fuzetec to ensure authenticity. Check for RoHS compliance documentation prior to final procurement approval.

Ptc Resettable Fuses Selection Notes

Select this component based on the required 350 mA hold current and 1812 surface mount form factor. Ensure the operating voltage does not exceed the rated limit of 16V for this specific suffix variant. Consider the concave package design for improved thermal dissipation and mechanical retention in dense layouts compared to standard flat packages.

Ptc Resettable Fuses Part Context

This part belongs to the FSMD series of surface mountable PTC resettable fuses. The series is engineered for compact electronic designs requiring reliable overcurrent protection. The FSMD035-R specifically utilizes the 1812 metric footprint, balancing size constraints with adequate current handling capabilities for portable and telecom applications.

Ptc Resettable Fuses Replacement Considerations

FSMD035-30-R serves as a related variant within the same series but differs in maximum voltage rating. Verify electrical compatibility before substitution. Other FSMD series parts may offer different current ratings or package sizes.
