Procurement Notes

Verify the specific suffix 'CEM3' against official Texas Instruments documentation to confirm the exact grade and temperature rating, as variations exist within the LM4041 family. Ensure compatibility with the required PCB footprint for the SOT-23 package. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component when a fixed 1.225 V reference is required in a compact SOT-23 package. It is suitable for designs needing extended temperature operation up to +125 °C with ±0.5% accuracy. Consider this part for applications where minimizing quiescent current is critical while maintaining stability across varying capacitive loads without additional external components.

Part Context

This component belongs to the LM4041-N series of precision micropower shunt voltage references from Texas Instruments. The series includes both fixed and adjustable versions available in SC-70 and SOT-23 packages. The LM4041-N series is designed to eliminate the need for external stabilizing capacitors, offering ease of use and stability with any capacitive load in space-saving form factors.
