AY1112H-TR

Overview

The AY1112H-TR is a single-color surface-mount LED manufactured by Stanley Electric Co. It emits yellow light with a peak wavelength of 580 nm and a dominant wavelength of 606 nm. The component features a diffused lens in a 2125 (0805 metric) package, measuring 2.0 mm x 1.25 mm x 0.9 mm. Typical forward voltage is 2.2 V at a test current of 20 mA. The device offers a viewing angle of approximately 153° to 154° and provides an optical intensity of 3.7 mcd.

Feature Summary

• Emits yellow light via a diffused lens for uniform visibility
• Designed for surface-mount assembly in compact footprints
• Rectangular lens shape with a flat top profile

Applications

• Panel indicator lights
• Status indication on electronic devices
• Instrumentation displays

Procurement Notes

Verify the exact datasheet version before integration, as manufacturing parameters may vary between production batches. Confirm that the 2125 package dimensions align with your PCB land pattern design. Ensure thermal management strategies account for the specific power dissipation characteristics of this yellow LED variant during continuous operation.

Selection Notes

Select this component when a standard 0805 footprint is required for yellow indication. Compare the 3.7 mcd intensity against application visibility needs. Consider the 2.2 V forward voltage drop for circuit driver compatibility. Verify moisture sensitivity level handling procedures if storage conditions exceed specified limits prior to soldering.

Part Context

This part belongs to Stanley Electric's 1112H series of single-color LEDs. It shares the same physical 2125 package form factor as other variants in the lineup, such as the AA1112H-TR (orange) and FKR1112H-TR (red). The series is characterized by standardized mounting dimensions while differing in semiconductor materials to achieve specific emission colors.
