AA3021SESK/J4-TR

Overview

The AA3021SESK/J4-TR is a single-color orange surface-mount LED manufactured by Kingbright. It operates at a forward current of 20 mA with a typical forward voltage of 2.1 V and a power rating of 75 mW. The component emits light at a peak wavelength of 601 nm, offering a luminous intensity of 400 mcd. It features a water-clear oval lens measuring 2.5 mm x 1.5 mm within a 1208 (3020 metric) package footprint of 3 mm x 2 mm x 1.3 mm. The device provides a viewing angle of 125 degrees and functions reliably between -40°C and +85°C.

Feature Summary

• Emits distinct orange light at a 601 nm peak wavelength for high visibility applications
• Features a water-clear oval lens to optimize light transmission and distribution
• Designed for surface-mount technology with a compact 1208 package profile

Applications

• Electronic equipment status indicators
• Instrument panel illumination
• Consumer appliance signaling

Procurement Notes

Verify the specific suffix J4-TR against official Kingbright documentation to confirm the exact optical and electrical characteristics. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Ensure the obsolete lifecycle status is acceptable for the intended design duration. Validate that the 1208 package dimensions align with the target PCB layout constraints.

Selection Notes

Select this component when a bright orange indicator is required in space-constrained designs. The 400 mcd intensity supports clear visibility in various ambient lighting conditions. The standard 20 mA drive current allows compatibility with common microcontroller GPIO pins without additional buffering. Consider the 125-degree viewing angle for broad visual indication needs.

Part Context

This part belongs to the Kingbright AA3021 series of single-color SMD LEDs. The series utilizes a standardized 1208 footprint to facilitate easy integration into modern printed circuit boards. Variants within this family differ primarily by lens color, wavelength, and brightness output while maintaining consistent mechanical dimensions.
