AA3021QBS/D

Overview

The Kingbright AA3021QBS/D is a single-color blue surface-mount LED in the 3020 (1208 metric) package. It emits light at a peak wavelength of 470 nm with a water clear oval lens. The component operates at a forward current of 20 mA and a forward voltage of 3.3 V, rated for 120 mW power dissipation. It provides an optical intensity of 230 mcd and features a 125-degree viewing angle. Physical dimensions are 3 mm in length, 2 mm in width, and 1.3 mm in height. It functions within a temperature range of -40 C to +85 C.

Feature Summary

• Utilizes a water clear oval lens to direct blue light emission.
• Designed for surface mount technology (SMD/SMT) assembly.
• Constructed with a colorless lens material for transparency.

Applications

• Indicator lights for electronic devices
• Backlighting applications requiring blue illumination
• Panel status indicators

Procurement Notes

Verify the specific suffix D against official Kingbright documentation to confirm exact binning or tolerance specifications. Confirm moisture sensitivity level handling requirements prior to soldering. Ensure compatibility with standard reflow profiles for SMD components. Cross-reference datasheet electrical limits to prevent overdriving the device during operation.

Selection Notes

Select this component when a compact 3020 footprint is required for blue indication. Compare forward voltage and luminous intensity against alternative 470 nm LEDs in similar packages. Evaluate thermal management needs given the 120 mW power rating. Verify that the 125-degree viewing angle meets visibility requirements for the target enclosure design.

Part Context

This part belongs to the Kingbright 3020 series of single-color LEDs. It shares the same physical package dimensions as other variants like the AA3021ES and AA3021SGS but differs in semiconductor material to produce blue light. The series offers various colors and intensities within the standardized 3.0 x 2.0 mm form factor.
