Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and packaging details as per the manufacturer's datasheet. Confirm the active status and availability through authorized distributors, as end-of-life notifications may apply to older revisions. Ensure the SOT-23-3 footprint matches the design requirements and check for moisture sensitivity level constraints during assembly.

Selection Notes

Select this component when a fixed 10 V reference with tight tolerance (±0.2%) is required in a compact SOT-23-3 package. It is suitable for industrial environments (-40°C to +85°C) where low power consumption and stability under varying capacitive loads are critical. Compare against other grades like A or C if different accuracy or temperature ranges are needed.
