Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status via official documentation. Check for obsolescence notices as availability may be limited. Ensure packaging specifications match project requirements. Validate datasheet revisions for accurate electrical characteristics before final design integration.

Selection Notes

Select this component when low quiescent current is critical for battery life extension. The fixed 3.1 V threshold suits applications requiring precise voltage supervision at standard logic levels. The SC-70-3 package offers space-efficient surface-mount solutions. Consider the 260 ms reset delay for system startup timing requirements. Verify compatibility with downstream circuit input thresholds.

Part Context
