Ptc Resettable Fuses Procurement Notes
Verify the specific voltage rating and package variant against official datasheets before procurement. Confirm that the 6V rating aligns with system requirements. Ensure the 1210 concave package dimensions match the PCB footprint. Cross-reference manufacturer part numbers to avoid confusion with similar series components.
Ptc Resettable Fuses Selection Notes
Select this component for low-voltage circuits requiring 1.5 A hold current protection. Consider the 6V maximum voltage limit when designing power paths. Evaluate thermal dissipation requirements in confined spaces due to the surface-mount form factor. Ensure compatibility with reflow soldering processes specified for the 1210 package.
Ptc Resettable Fuses Part Context
This part belongs to the FSMD series of polymeric PTC resettable fuses from RFE/Fuzetec. The series provides overcurrent protection solutions for various electronic applications. The 1210 designation indicates the standard surface-mount package size used for compact circuit board designs.
Ptc Resettable Fuses Replacement Considerations
FSMD150-1206R offers similar electrical characteristics in a smaller 1206 package. FSMD175-1210R provides a higher hold current within the same package footprint. Verify voltage ratings and physical dimensions when substituting.
