Voltage Reference Procurement Notes

Verify the specific suffix 'EMFX' confirms the tape-and-reel packaging format intended for automated assembly processes. Ensure the 'NOPB' designation indicates lead-free construction compliant with RoHS standards. Confirm that the 2.048V output variant matches the circuit design requirements before procurement.

Voltage Reference Selection Notes

Select this component when a compact SOT-23-5 footprint is required alongside high accuracy specifications. The 30 ppm/°C temperature coefficient makes it suitable for environments where thermal stability is critical. Compare against other LM4132 variants if different output voltages or tighter accuracy grades are needed.

Voltage Reference Part Context

This part belongs to the LM4132 family of micropower series voltage references from Texas Instruments. The family offers various output voltages and accuracy grades within the same small form factor. The LM4132 series is designed to replace larger, less efficient reference solutions in space-constrained electronic designs.

Voltage Reference Replacement Considerations

Direct substitutes include other LM4132 variants such as LM4132AMF-2.0/NOPB or LM4132CMF-2.0/NOPB, which share the same pinout and package but may differ in accuracy grade or temperature coefficient specifications.
