Voltage Reference Procurement Notes

Verify the specific suffix #WTRMPBF indicates automotive grade qualification and mini tape-and-reel packaging containing 500 units. Confirm the H-grade designation corresponds to the specified -40°C to +125°C operating range. Ensure compatibility with SOT-23-6 footprint requirements during procurement validation.

Voltage Reference Selection Notes

Select this component when a stable 3.3V reference is required in space-constrained designs utilizing the SOT-23 package. It is suitable for applications demanding high accuracy without shutdown functionality. Consider the B-grade specifications if 20ppm/°C drift meets system tolerance requirements compared to the higher precision A-grade options.

Voltage Reference Part Context

This part belongs to the LT6654 family of small precision voltage references designed for portable and industrial equipment. The family includes various output voltages and packages, such as the LS8 hermetic option. The HS6 variant specifically targets automotive environments with controlled manufacturing processes to ensure reliability under harsh conditions.

Voltage Reference Replacement Considerations

LT6654BHS6-3.3#WTRPBF offers identical electrical characteristics but utilizes standard tape-and-reel packaging instead of the mini reel format.
