Voltage Reference Procurement Notes

Verify that the specific part number includes the NOPB suffix to confirm lead-free status and compliance with RoHS directives. Confirm the 'C' grade designation matches the required ±0.5% initial tolerance specification. Ensure the industrial temperature range (-40°C to 85°C) aligns with the operational environment requirements before finalizing procurement.

Voltage Reference Selection Notes

Select this component when space constraints require a sub-miniature SOT-23 package. Choose this model if the application demands a fixed 4.096 V reference without requiring output capacitor stabilization. Consider the C-grade tolerance specifications against system accuracy requirements and verify that the industrial temperature range meets the environmental conditions.
