AA3022YC-4.5SF

Overview

The Kingbright AA3022YC-4.5SF is a single-color surface-mount LED lamp emitting yellow light. It utilizes a PLCC-2 (1208 metric) package with dimensions of 3.0 mm x 2.2 mm x 1.5 mm. The component features a water-clear rectangular lens and a white reflector designed to maximize light output. Key electrical parameters include a forward voltage of 2.2 V at a forward current of 20 mA, resulting in a power rating of 62.5 mW. The device operates within a temperature range of -40°C to +85°C and exhibits a viewing angle of 120 degrees.

Feature Summary

• Utilizes a compact 3.0mm x 2.2mm SMD form factor for space-efficient PCB layouts
• Incorporates a white reflector structure to enhance luminous intensity
• Features a water-clear rectangular lens for consistent light transmission
• Designed for reliable operation across extended industrial temperature ranges

Applications

• Panel indicator lights for electronic equipment
• Status indication in consumer appliances
• Instrumentation display modules
• General-purpose visual signaling systems

Procurement Notes

Verify the specific suffix configuration against official Kingbright documentation to ensure compatibility with required optical and electrical specifications. Confirm RoHS compliance status and moisture sensitivity level prior to storage and assembly. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability. Ensure that handling procedures adhere to recommended reflow soldering profiles to maintain component integrity during manufacturing processes.

Selection Notes

Select this component when a low-profile yellow indicator is required for surface-mount assembly. The 120-degree viewing angle provides broad visibility suitable for panel applications. Consider the 2.2V forward voltage drop for circuit design calculations. The standard PLCC-2 footprint allows for easy integration into existing designs utilizing similar LED packages. Evaluate thermal management requirements based on the specified maximum operating temperature limit.

Part Context

This part belongs to Kingbright's 3.0x2.2mm single-color surface-mount LED series. It shares the physical PLCC-2 package dimensions with other variants such as the AA3022SGS-4.5SF (green) and KA-3022SURSK-4.5SF (red). The series is characterized by its compact size and standardized pin spacing, facilitating automated placement. Differentiation between variants is primarily determined by the semiconductor material determining the emission color and wavelength.

Replacement Considerations

Direct substitutes within the same package family include AA3022SRC-4.5SF (Red) or AA3022SGS-4.5SF (Green) if color change is acceptable. Verify that any alternative maintains the 3.0x2.2mm footprint and compatible forward voltage characteristics. Consult official Kingbright cross-reference guides for confirmed equivalent parts.
