Voltage Reference Procurement Notes

Verify the specific suffix 'MFR' indicates reel packaging when ordering. Confirm the 'Q1' designation aligns with required automotive qualification standards for your application. Ensure the 3.3V output matches system requirements. Check lead times as manufacturing cycles may vary. Validate RoHS compliance status through official documentation before integration.

Voltage Reference Selection Notes

Select this component when automotive certification and high precision are mandatory. The 20ppm/°C temperature coefficient offers superior stability compared to standard industrial parts. Consider the 100µA supply current for power-sensitive designs. The SOT-23-5 package limits thermal dissipation, so verify junction temperature calculations under load conditions.
