AA4040SURCK

Overview

The AA4040SURCK is a single-color red LED from Kingbright, designed for surface-mount technology in a PLCC-2 package. It features a water-clear dome lens with a 2.4 mm diameter and emits light at a peak wavelength of 645 nm. The component has dimensions of 4.0 mm length, 3.6 mm width, and 4.0 mm height. Electrical characteristics include a forward voltage of 1.95 V and a forward current rating of 20 mA. It offers a viewing angle of 120 degrees and an optical intensity of 200 mcd.

Feature Summary

• Utilizes a water-clear dome lens to provide a wide 120-degree viewing angle for effective visibility.
• Constructed in a compact PLCC-2 surface-mount package suitable for dense circuit board layouts.
• Emits pure red light at a 645 nm peak wavelength with high optical intensity.

Applications

• Panel indicator lights
• Status indication in electronic devices
• Instrumentation displays

Procurement Notes

Verify the specific suffix configuration against official Kingbright documentation to ensure correct lens transparency and emission color specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Cross-reference datasheet parameters such as forward voltage and peak wavelength to match design constraints accurately.

Selection Notes

Select this component when a standard red SMD LED with a 120-degree viewing angle is required. Ensure the PLCC-2 footprint matches the PCB layout. Consider the 1.95 V forward voltage drop for circuit design. Verify thermal management needs as the maximum operating temperature reaches +85 C.

Part Context

This part belongs to the AA4040 series of single-color LEDs manufactured by Kingbright. The series utilizes a 4x4 mm form factor with a PLCC-2 package style. It represents a standard solution for surface-mount applications requiring reliable red light emission in consumer and industrial electronics.

Replacement Considerations

Consult official Kingbright substitution guides for verified alternatives. Generic cross-references may not match exact electrical or mechanical specifications. Verify pinout compatibility and spectral output before implementing any substitute components.
