Voltage Reference Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status and manufacturing origin against official datasheets. Ensure storage conditions maintain moisture sensitivity level integrity prior to soldering. Validate part marking matches the specific suffix configuration for the 4.1V variant.

Voltage Reference Selection Notes

Select this component when a fixed 4.096V reference is required in space-constrained designs. The SOT-23-3 package offers a small footprint suitable for dense PCB layouts. Consider the 50 ppm/°C temperature coefficient for environments with moderate thermal variations. Ensure circuit design accommodates the 15 mA maximum shunt current capability.

Voltage Reference Part Context

This part belongs to the LM4050 series of precision micropower shunt voltage references. The series includes various output voltage options and accuracy grades. The 'B' designation typically indicates a specific accuracy bin, while the 'M3' denotes the SOT-23-3 package type. The '+T' suffix often refers to tape-and-reel packaging, though specific packaging details should be confirmed with the supplier.
