AA4040QBS/D-AMT

Overview

The Kingbright AA4040QBS/D-AMT is a single-color blue surface-mount LED from the KA-4040 series. It features a PLCC-2 package with dimensions of 4.0 x 4.0 mm and a height of 4 mm. The component emits light at a peak wavelength of 460 nm with a water clear dome lens. Electrical characteristics include a forward voltage of 3.3 V at a forward current of 20 mA, resulting in a power rating of 120 mW. Optical performance specifies an intensity of 300 mcd and a viewing angle of 120 degrees. It operates within a temperature range of -40 °C to +85 °C.

Feature Summary

• Utilizes a compact PLCC-2 surface mount package for efficient PCB space utilization.
• Features a water clear dome lens to provide a wide 120-degree viewing angle.
• Delivers high-intensity blue emission suitable for visible indicator applications.

Applications

• Panel status indicators
• Instrumentation displays
• Consumer electronics signaling

Procurement Notes

Verify the specific suffix D-AMT against official Kingbright documentation to confirm exact binning or packaging specifications. Ensure compatibility with standard SMD reflow soldering profiles. Confirm RoHS compliance status through the manufacturer's latest datasheet before integration into regulated products.

Selection Notes

Select this component when a standard blue SMD LED with a wide viewing angle is required. The PLCC-2 form factor allows for easy replacement of older through-hole designs. Consider the 3.3 V forward voltage drop for appropriate current limiting resistor calculations in the circuit design.

Part Context

This part belongs to the Kingbright KA-4040 series, which offers various color options in a standardized 4x4 mm footprint. The series provides consistent mechanical dimensions across different wavelengths, facilitating design flexibility while maintaining uniform board layout requirements for multi-color assemblies.

Replacement Considerations

Direct substitutes include other Kingbright KA-4040 series variants such as AA4040QBS/D or AA4040QBS/G, provided the specific luminous intensity and wavelength tolerances match the application requirements. Verify pinout compatibility before substitution.
