Procurement Notes

This specific part number is officially listed as discontinued by the manufacturer. Verification of availability should focus on remaining stock or authorized distributors rather than direct new production orders. Engineers must confirm the End-of-Life status and review any Product Change Notices regarding replacement components before finalizing designs.

Selection Notes

Select this component when design requirements prioritize extreme low-noise performance and tight initial accuracy over cost or volume availability. The 3ppm/°C temperature coefficient makes it suitable for environments with significant thermal fluctuations. Consider alternative active products if long-term supply continuity is a critical project constraint.

Part Context
