Procurement Notes

Verify the specific ordering suffix 'BK TIN/LEAD' to confirm the tin/lead plating option required by your assembly process. Ensure compatibility with RoHS directives if lead-free alternatives are mandated. Confirm availability status as manufacturing transitions may affect long-term supply continuity.

Selection Notes

Select this component when a 6.8 V reference with ±5% accuracy is required in a standard axial leaded package. Consider the 1.0 W power dissipation limit and the positive temperature coefficient for thermal design calculations. Verify that the DO-41 footprint matches the target PCB layout constraints.
