AA4040MGS

Overview

The AA4040MGS is a single-color green surface-mount LED manufactured by Kingbright. It features a PLCC-2 package with dimensions of 4.0 mm x 4.0 mm x 4.0 mm and a 2.4 mm dome lens. The component emits light at a wavelength of 570 nm with a viewing angle of 120 degrees. Key electrical parameters include a forward current of 20 mA, a forward voltage of 2.1 V, and a power rating of 75 mW. Luminous intensity is specified at 120 mcd. The lens is water clear, and the device operates within a temperature range of -40°C to +85°C.

Feature Summary

• Surface mount design in a compact PLCC-2 package for automated assembly
• Water clear dome lens providing a 120-degree viewing angle
• RoHS compliant construction suitable for standard electronic manufacturing

Applications

• Panel indicator lights
• Instrumentation status displays
• Consumer electronics illumination

Procurement Notes

Verify the specific datasheet version for the AA4040MGS to confirm moisture sensitivity levels and reflow soldering profiles. Ensure that the ordering suffix matches the required packaging format, such as cut tape or reel, as availability may vary by distributor. Cross-reference the manufacturer part number with authorized supplier catalogs to confirm current production status and compliance certifications before finalizing procurement.

Selection Notes

Select this component when a standard 4x4 mm green SMD LED is required for general indication purposes. The 120-degree viewing angle offers broad visibility compared to narrower beam LEDs. Consider the 2.1 V forward voltage drop for circuit design calculations. This part is suitable for applications where space constraints require a low-profile surface mount solution with reliable performance across standard operating temperatures.

Part Context

The AA4040 series represents Kingbright's line of 4.0 x 4.0 mm surface mount LEDs. The MGS suffix specifically denotes the green color variant within this family. These components are designed for high-volume manufacturing processes, offering consistency in optical and electrical characteristics. The series utilizes InGaN materials to achieve efficient green light emission in a standardized footprint compatible with existing SMT lines.

Replacement Considerations

Direct substitutes should maintain the PLCC-2 package, 570 nm wavelength, and similar luminous intensity. Verify pin compatibility and thermal resistance if replacing with parts from other manufacturers.
