Ptc Resettable Fuses Procurement Notes

Verify the specific datasheet version for the FSMD110-16-R to confirm electrical tolerances and thermal characteristics. Ensure the selected component matches the required 1812 footprint and 16V rating for the target application design.

Ptc Resettable Fuses Selection Notes

Select this part when a 1.1 A hold current and 16 V rating are required for surface mount overcurrent protection. Verify that the inrush current profile of the load does not exceed the trip threshold of 2.2 A to prevent nuisance tripping during normal operation.

Ptc Resettable Fuses Part Context

This component belongs to the FSMD1812 series of surface mountable PTC resettable fuses manufactured by RFE/Fuzetec. The series provides various hold current options within the 1812 package format for different voltage ratings.

Ptc Resettable Fuses Replacement Considerations

Cross-reference with other FSMD1812 series variants if different hold currents are needed. Ensure substitute parts maintain the same 16V rating and 1812 package dimensions for direct compatibility.
