Voltage Reference Procurement Notes

Verify the specific suffix 'MFR' indicates reel packaging when ordering. Confirm AEC-Q100 qualification status aligns with target automotive application requirements. Ensure input voltage does not exceed the 5.5 V maximum rating during operation. Check for RoHS compliance documentation if environmental regulations apply to the end product.

Voltage Reference Selection Notes

Select this component when automotive certification and tight initial accuracy are critical. Compare against non-automotive variants if cost sensitivity outweighs reliability needs. Consider the 20 ppm/°C temperature coefficient for applications experiencing significant thermal cycling. Evaluate the SOT-23-5 footprint constraints against available board space.
