IN-S121ASYG

LED Indication - Discrete Overview

The IN-S121ASYG is a side-view surface-mount LED from Inolux, housed in a compact 1208 package. It emits yellow-green light at a wavelength of 576 nm with a typical forward voltage of 2.2 V and a test current of 20 mA. The component features a clear lens with a viewing angle of 120 degrees and delivers a luminous intensity of 40 mcd. Its rectangular lens measures 2.00 mm by 1.00 mm, with a maximum height of 1.00 mm, making it suitable for space-constrained designs.

LED Indication - Discrete Feature Summary

• Side-view emission configuration optimized for visibility in tight spaces
• Clear domed top lens design enhances light transmission
• Wide 120-degree viewing angle ensures broad visual coverage

LED Indication - Discrete Applications

• Consumer electronics status indication
• Industrial equipment signaling
• Space-constrained device interfaces

LED Indication - Discrete Procurement Notes

Verify the specific ordering suffix to confirm the exact color bin and packaging format. Ensure compatibility with standard SMD reflow profiles during assembly. Cross-reference the datasheet for absolute maximum ratings to prevent thermal damage. Confirm lead-free compliance if required by your manufacturing standards.

LED Indication - Discrete Selection Notes

Select this component when a low-profile, side-emitting indicator is required. The 1208 package size suits applications with limited board real estate. Consider the 2.2 V forward voltage drop for circuit power budgeting. The wide viewing angle supports visibility from multiple positions without precise alignment.

LED Indication - Discrete Part Context

This part belongs to the IN-S121AS series of surface-mount LEDs. The series offers various color options within the same 1208 footprint. It is designed for high-volume production environments requiring consistent optical performance. The side-view orientation distinguishes it from top-emitting variants in the same family.

LED Indication - Discrete Replacement Considerations

Direct substitutes include other 1208 package side-view LEDs with matching electrical characteristics. Verify that alternative parts maintain the 120-degree viewing angle and similar luminous intensity. Check for compatible mounting dimensions to ensure mechanical fit. Confirm spectral consistency if color accuracy is critical.
