AA4040LQBS/D-AMT

LED Indication - Discrete Overview

The AA4040LQBS/D-AMT is a single-color blue surface-mount LED from Kingbright. It operates at a forward current of 20 mA with a typical forward voltage of 2.65 V and a power rating of 120 mW. The component emits light at a wavelength of 463 nm to 475 nm. It features a water-clear lens with a dome shape and a viewing angle of 120 degrees. The physical dimensions are 4.0 mm in width, 3.6 mm in length, and 4.1 mm in height. The device is housed in a 2-SMD right-angle package.

LED Indication - Discrete Feature Summary

• Right-angle surface-mount configuration for flexible PCB layout
• Water-clear dome lens for optimized light transmission
• Standard PLCC-2 compatible footprint design

LED Indication - Discrete Applications

• Panel indicator lighting
• Status indication on electronic devices
• General-purpose visual signaling

LED Indication - Discrete Procurement Notes

Verify the specific suffix D-AMT against the manufacturer's latest datasheet to confirm lead time and availability status. Ensure the right-angle pin configuration matches the target PCB footprint requirements. Check RoHS compliance documentation for environmental regulations. Confirm moisture sensitivity level handling procedures during storage and assembly.

LED Indication - Discrete Selection Notes

Select this component when a right-angle LED orientation is required for space-constrained designs. The 4x4 mm form factor allows for standard placement while directing light perpendicular to the board. Consider the 120-degree viewing angle for visibility requirements. Evaluate the 2.65 V forward voltage drop for circuit power budgeting.

LED Indication - Discrete Part Context

This part belongs to Kingbright's AA4040 series of single-color LEDs. The series offers various color options within a standardized 4x4 mm package size. The AA4040LQBS/D-AMT specifically provides blue emission characteristics suitable for high-visibility applications requiring a compact form factor.

LED Indication - Discrete Replacement Considerations

Direct substitutes include other Kingbright AA4040 series variants with matching right-angle pin configurations. Verify electrical parameters such as forward voltage and luminous intensity before substitution. Ensure the replacement part maintains the same mechanical dimensions and mounting style.
