AAA3528LSEEZGKQBKS

Overview

The AAA3528LSEEZGKQBKS is a low copper RGB surface-mount LED from Kingbright, housed in a 1411 (3.5mm x 2.8mm) package with a height of 1.9 mm. It features a water-clear round flat lens and offers a 120-degree viewing angle. Electrical characteristics include forward currents of 2 mA, forward voltages of 2.1 V, 3.1 V, and 3.1 V for the respective colors, and power ratings ranging from 120 mW to 125 mW. The component emits red at 621 nm (20 mcd), green at 525 nm (180 mcd), and blue at 465 nm (30 mcd). It operates between -40 C and +85 C and is moisture sensitive.

Feature Summary

• Integrates three distinct light-emitting diodes within a single compact surface-mount package to enable multi-color output.
• Utilizes a low copper lead frame construction designed to enhance solderability during reflow processes.
• Features a water-clear lens with a wide 120-degree viewing angle for consistent optical performance.

Applications

• Status indication in consumer electronic devices
• Backlighting applications requiring mixed color generation
• Indicator lights for control panels and interfaces

Procurement Notes

Verify the specific suffix KQBKS against the manufacturer datasheet to confirm the low copper lead frame specification. Ensure handling procedures account for the stated moisture sensitivity level to prevent damage during storage and assembly. Cross-reference the exact wavelength and intensity values with the official Kingbright documentation prior to finalizing design specifications.

Selection Notes

Select this component when a compact RGB solution is required for designs utilizing standard 3528 footprints. The low copper construction supports improved thermal management and solder joint reliability compared to standard variants. Confirm that the 2 mA forward current requirement aligns with the target circuit drive capabilities and brightness expectations.

Part Context

This part belongs to the HeliColour series by Kingbright, which focuses on high-reliability multi-color LEDs. The 3528 form factor is widely adopted in the electronics industry for space-constrained surface-mount applications. The specific designation indicates a variant optimized for manufacturing robustness through material selection.

Replacement Considerations

Standard RGB 3528 LEDs may serve as functional substitutes if the low copper lead frame is not critical. Verify that alternative parts match the 3.5mm x 2.8mm dimensions and 1.9mm height to ensure board compatibility. Check electrical parameters such as forward voltage and current limits to avoid circuit modification.
