AA4040SYCK

Overview

The AA4040SYCK is a single-color surface-mount LED from the Kingbright AA4040 series, designed for right-angle installation. It emits yellow light with a peak wavelength of 590 nm and features a water-clear lens. The component operates at a typical forward voltage of 2 V with a forward current of 20 mA. It has a power rating of 75 mW and a viewing angle of 120 degrees. The package dimensions are 4.00 mm in length, 3.60 mm in width, and 4.00 mm in maximum height.

Feature Summary

• Right-angle surface mount configuration for compact PCB layouts
• Water-clear dome lens for optimized light transmission
• High brightness yellow emission suitable for indicator applications

Applications

• Electronic device status indicators
• Control panel signal lights
• Appliance front panel displays

Procurement Notes

Verify the specific suffix against the manufacturer datasheet to confirm exact binning and packaging details. Ensure compatibility with standard SMT reflow profiles and check moisture sensitivity level requirements prior to assembly. Confirm RoHS compliance status with the latest product change notifications.

Selection Notes

Select this component when a right-angle footprint is required to save board space or facilitate specific connector alignments. Compare the 590 nm yellow output against other available colors in the AA4040 family. Consider the 120-degree viewing angle for visibility requirements in the final enclosure design.

Part Context

This part belongs to the AA4040 series of second-generation SMD LEDs, which offer improved material durability and electrical reliability compared to previous iterations. The series provides various color options and mounting styles to support dense system designs in consumer electronics and industrial equipment.

Replacement Considerations

Direct substitutes within the same series include AA4040SYSK and AA4040SYCKT/J3-AMT. Verify pinout orientation and mechanical tolerance differences before swapping components in existing designs.
