AA3528SYCKT09

Overview

The AA3528SYCKT09 is a single-color yellow surface-mount LED manufactured by Kingbright. It features a 1311 (3228 metric) package with dimensions of 3.2 mm length, 2.8 mm width, and 1.9 mm height. The device emits light at a wavelength of 605 nm with a water-clear lens. Key electrical parameters include a forward current of 20 mA, a forward voltage of 2.1 V, and a power rating of 75 mW. It provides an optical intensity of 350 mcd with a viewing angle of 120 degrees. The component operates within a temperature range of -40°C to +85°C.

Feature Summary

• Features a Z-bend lead frame configuration for secure surface mounting.
• Utilizes a water-clear round flat lens to maintain optical clarity.
• Designed for high-intensity yellow illumination applications.

Applications

• Indicator lighting in electronic devices
• Status indication on control panels
• General-purpose visual signaling

Procurement Notes

Verify the specific suffix KT09 to confirm the Z-bend lead form factor and reel packaging type. Ensure compatibility with standard SMD reflow soldering profiles. Confirm moisture sensitivity handling requirements prior to assembly. Cross-reference the 3228 metric package dimensions against PCB footprint specifications. Validate that the 605 nm peak wavelength meets the required color specification for the target application.

Selection Notes

Select this component when a yellow indicator with enhanced mechanical retention via Z-bend leads is required. Consider the 350 mcd intensity for visibility needs. The 3228 package offers a compact alternative to the standard 3528 size. Verify thermal management capabilities given the 75 mW power rating. Ensure the 2.1 V forward voltage aligns with the driving circuit design constraints.

Part Context

This part belongs to Kingbright's HELI-R series of surface-mount LEDs. It shares the 3228 metric package family with other variants like the AA3528SECKT09. The series focuses on providing reliable single-color indicators with specific mechanical configurations such as bent leads for improved solder joint integrity during automated placement processes.

Replacement Considerations

AA3528SYC is a similar variant but lacks the Z-bend lead configuration and specific reel packaging indicated by the KT09 suffix. Verify mechanical fit and optical characteristics before substitution.
