Voltage Reference Procurement Notes

Verify the specific suffix 'X' against the manufacturer's official documentation to confirm packaging details such as reel or cut tape specifications. Ensure the component meets the required RoHS compliance standards for your region. Confirm that the B-grade tolerance aligns with circuit requirements before finalizing procurement orders.

Voltage Reference Selection Notes

Select this component when space constraints require a sub-miniature SOT-23 package. Choose the B grade for applications requiring ±0.2% initial accuracy. Verify that the minimum operating current of 100 μA fits within the system's power budget and that the 15 mA maximum cathode current accommodates the worst-case load conditions.
