Voltage Reference Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix indicates the correct accuracy grade and package variant. Check for RoHS compliance status and ensure the part matches the required thermal and electrical specifications for the target application environment before procurement.

Voltage Reference Selection Notes

Select this component when a compact SOT-23 footprint is required alongside high precision. Compare against the LM4132AMF variant if tighter initial accuracy is needed, or the LM4132CMF if lower cost is prioritized over precision. Ensure the 20 mA load capability meets the circuit requirements.

Voltage Reference Part Context

This part belongs to the LM4132 family of micropower series voltage references designed for space-constrained applications. It shares the same pinout and general architecture as other variants in the series, differing primarily in accuracy grades and output voltage options. The BMF suffix denotes a specific accuracy bin within the SOT-23-5 package configuration.

Voltage Reference Replacement Considerations

LM4132AMF-2.0/NOPB offers higher initial accuracy (±0.05%). LM4132CMF-2.0/NOPB provides a lower-cost option with reduced accuracy (±0.5%). Verify pin compatibility and thermal characteristics when substituting.
