• RoHS compliant and halogen-free composition

Ptc Resettable Fuses Applications

• Protection for high-density circuit boards
• Overcurrent protection in portable electronic devices
• Circuit safeguarding in consumer electronics

Ptc Resettable Fuses Procurement Notes

Verify the specific voltage and current ratings against the application requirements, as the FSMD1206 series includes variants with different specifications such as 48V or 6V options. Confirm that the 1A hold current aligns with the normal operating load. Ensure the 1206 package dimensions fit the PCB footprint constraints. Check for RoHS compliance documentation if required by regulatory standards.

Ptc Resettable Fuses Selection Notes

Select this component when a low-voltage (6V) overcurrent protection solution is needed for compact designs. The 1A hold current suits moderate power applications. Consider the 300ms trip time for circuits tolerant of brief surge currents. The 1206 form factor allows for space-constrained layouts compared to larger through-hole fuses.

Ptc Resettable Fuses Part Context

This part belongs to the FSMD1206 series of surface-mountable PTC resettable fuses. The series offers various hold currents and voltage ratings to suit different circuit protection needs. The FSMD100-1206R specifically targets applications requiring 6V operation and 1A continuous current handling.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other FSMD1206 series parts with matching 6V and 1A ratings, such as FSMD016-1206-R if lower current is acceptable. Verify package compatibility and electrical parameters before substitution.
