AA4040SRS

Overview

The Kingbright AA4040SRS is a single-color surface-mount LED in the PLCC-2 package. It emits red light with a peak wavelength of 630 nm and a viewing angle of 120 degrees. The component operates at a forward current of 20 mA with a forward voltage of 1.95 V and a power rating of 75 mW. It features a water-clear dome lens and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Surface-mount design in a compact PLCC-2 package for automated assembly
• Water-clear dome lens provides a wide 120-degree viewing angle
• Red emission optimized for indicator applications

Applications

• Panel indicators
• Status lights
• Instrumentation displays

Procurement Notes

Verify the specific suffix against official Kingbright documentation, as variants like SURSK or SRSYKCT-R differ in luminous intensity and wavelength. Confirm RoHS compliance status and moisture sensitivity levels prior to procurement to ensure compatibility with reflow soldering profiles.

Selection Notes

Select this component for standard red indication where a 120-degree visibility cone is required. Ensure the circuit limits current to 20 mA to maintain the 75 mW power rating. Verify that the 1.95 V forward voltage aligns with the system drive logic.
