AA3021SYSK/J3-TR

Overview

The AA3021SYSK/J3-TR is a single-color yellow light-emitting diode manufactured by Kingbright, designed for surface-mount technology applications. It features a clear water lens with an oval shape and flat top, emitting light at a peak wavelength of 590nm. The component operates with a typical forward voltage of 2V at a test current of 20mA, producing a luminous intensity of 200mcd. It has a viewing angle of 125 degrees and is housed in a compact 1208 (3020 metric) package measuring 3.0mm in length, 2.0mm in width, and 1.3mm in height.

Feature Summary

• Emits distinct yellow light with high clarity through a water-clear oval lens
• Designed for reliable surface-mount integration on printed circuit boards
• Provides wide-angle illumination suitable for general indicator purposes

Applications

• Panel status indicators for electronic equipment
• Power supply status signaling
• General-purpose visual indication in consumer devices

Procurement Notes

Verify the exact part number suffix to ensure compatibility with specific lens color and packaging requirements. Confirm RoHS compliance status and moisture sensitivity level handling procedures prior to assembly. Cross-reference datasheet electrical characteristics against circuit design limits to prevent overdriving. Ensure storage conditions meet manufacturer specifications to maintain component integrity before soldering.

Selection Notes

Select this component when a standard yellow indicator with moderate brightness is required for surface-mount designs. Consider the 125-degree viewing angle for visibility requirements. Evaluate the 2V forward voltage drop against available drive voltages. Compare physical dimensions against board space constraints to ensure proper footprint alignment during layout.

Part Context

This LED belongs to the Kingbright 3021 series, which offers various color options in a standardized 1208 SMD package. The series provides consistent mechanical dimensions across different wavelengths, facilitating design flexibility. The AA3021SYSK variant specifically targets yellow emission applications within this family.

Replacement Considerations

Direct substitutes include other Kingbright 3021 series yellow LEDs such as AA3021SYSK without the J3-TR suffix for bulk reel variations. Verify equivalent electrical parameters and mechanical footprint compatibility before substitution.
