AA3528YS

LED Indication - Discrete Overview

The AA3528YS is a single-color yellow surface-mount LED manufactured by Kingbright. It features a water-clear lens with a round flat shape and emits light at a wavelength of 588 nm. The component has a luminous intensity of 20 mcd, a forward voltage of 2.1 V, and operates at a forward current of 20 mA. Rated for 75 mW power dissipation, it measures 3.5 mm in length, 2.8 mm in width, and 1.9 mm in height. The device offers a viewing angle of 120 degrees and functions within a temperature range of -40°C to +85°C.

LED Indication - Discrete Feature Summary

• Emits yellow light with a 588 nm peak wavelength through a water-clear lens.
• Designed for surface-mount technology (SMD/SMT) installation.
• Provides a wide 120-degree viewing angle for broad visibility.

LED Indication - Discrete Applications

• PCB status indicators
• Panel indicator lights
• General-purpose visual signaling

LED Indication - Discrete Procurement Notes

Verify the specific part number AA3528YS against official Kingbright documentation to confirm electrical parameters such as forward voltage and luminous intensity. Ensure compatibility with RoHS standards and check moisture sensitivity levels before assembly. Confirm that the supplier provides valid datasheets matching the manufacturer's specifications to avoid counterfeit components.

LED Indication - Discrete Selection Notes

Select this component when a standard yellow SMD LED is required for panel or board indication. Consider the 2.1 V forward voltage and 20 mA operating current for circuit design. The 120-degree viewing angle makes it suitable for applications requiring wide visibility. Verify thermal limits and humidity sensitivity requirements for the intended environment.
