AA3021SYSK

Overview

Kingbright AA3021SYSK is a single-color yellow surface-mount LED in the KA-3021 series. It features a water-clear oval lens with dimensions of 3.0 mm length, 2.0 mm width, and 1.3 mm height. The component emits light at a peak wavelength of 590 nm with an intensity of 200 mcd. Electrical characteristics include a forward voltage of 2 V and a maximum power dissipation of 75 mW at a forward current of 20 mA. It operates within a temperature range of -40°C to +85°C and offers a viewing angle of 125 degrees.

Feature Summary

• Compact SMD form factor suitable for dense circuit board layouts
• Water-clear oval lens provides wide 125-degree visibility
• RoHS compliant construction for environmental safety

Applications

• Panel indicator lights
• Status signaling in consumer electronics
• Instrumentation displays

Procurement Notes

Verify the specific suffix against official Kingbright documentation to confirm optical and electrical tolerances. Confirm RoHS compliance status directly with the manufacturer or authorized distributor before integration. Ensure ESD handling protocols are followed during assembly due to moisture sensitivity classification.

Selection Notes

Select this component when a low-profile yellow indicator is required for space-constrained designs. The 20 mA drive current and 2 V forward voltage align with standard logic-level driving circuits. Consider the 125-degree viewing angle for applications requiring broad visual accessibility from multiple positions.

Part Context

The AA3021SYSK belongs to the KA-3021 family of surface-mount LEDs. This series is characterized by its small 1208 (3020 metric) package size, making it ideal for modern miniaturized electronic devices. The part utilizes standard lead-free soldering processes compatible with industrial reflow standards.

Replacement Considerations

AA3021YS is a verified substitute offering similar yellow emission characteristics within the same package footprint.
