LED Indication - Discrete Procurement Notes

Verify the specific datasheet version to confirm exact wavelength and intensity tolerances, as supplier listings may vary slightly between 601 nm and 605 nm specifications. Ensure compatibility with moisture sensitivity levels if storage conditions exceed recommended limits. Cross-reference the manufacturer part number AA4040SESK with distributor codes to avoid ordering errors related to tape and reel packaging variations.

LED Indication - Discrete Selection Notes

Select this component when an orange indication signal is required in a standard PLCC-2 footprint. The 2.1 V forward voltage aligns with common logic-level driving circuits. Consider the 90-degree viewing angle for visibility requirements. Verify that the 400 mcd intensity meets the ambient lighting conditions of the target application without requiring additional optics.

LED Indication - Discrete Part Context

This part belongs to Kingbright's AA series of single-color LEDs, which are designed for general-purpose indication. The series utilizes standard PLCC-2 packages to facilitate easy integration into existing PCB layouts. The AA4040SESK specifically targets applications needing reliable orange illumination with standardized electrical parameters compatible with widespread driver ICs.
