AA4040SURCKT-AMT

Overview

The Kingbright AA4040SURCKT-AMT is a single-color red light-emitting diode designed for surface-mount technology applications. It utilizes a PLCC-2 package with dimensions of 3.6 mm in length, 4 mm in width, and 4 mm in height. The component emits red light at a peak wavelength of 645 nm with a water clear dome lens that provides a 120-degree viewing angle. Electrical characteristics include a forward current rating of 20 mA and a forward voltage of 1.95 V. The unit delivers an optical intensity of 200 mcd and operates within a temperature range of -40 °C to +85 °C.

Feature Summary

• Surface-mount construction in a compact PLCC-2 package suitable for automated assembly processes
• Water clear dome lens design providing a wide 120-degree viewing angle for enhanced visibility
• Red emission profile optimized for standard indicator and display applications

Applications

• Panel status indicators
• Equipment power state signaling
• General purpose visual alerts

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact binning and packaging specifications. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Confirm moisture sensitivity levels and storage requirements prior to assembly to maintain component reliability during manufacturing.

Selection Notes

Select this component when a standard red indicator with high visibility is required in space-constrained designs. The PLCC-2 form factor allows for dense board layouts while maintaining robust mechanical stability. Consider the 120-degree viewing angle for applications requiring broad visual coverage from multiple positions.

Part Context

This part belongs to the Kingbright AA4040 series of second-generation SMD LEDs. The series offers improved material durability and electrical reliability compared to previous iterations. These components are engineered for dense system designs where consistent performance and long-term stability are critical for industrial and commercial electronics.

Replacement Considerations

Consult official Kingbright documentation for verified substitute part numbers. Cross-referencing requires matching package dimensions, electrical parameters, and optical characteristics to ensure functional equivalence without redesigning the host circuit board.
