150040YS73220

Overview

Würth Elektronik part number 150040YS73220 is a yellow single-color surface-mount LED from the WL-SMCC series. It features a 0402 (1005 metric) package with dimensions of 1.00mm length, 0.50mm width, and a maximum height of 0.35mm. The device emits light at a peak wavelength of 591nm with a viewing angle of 120 degrees. Electrical characteristics include a typical forward voltage of 2V at a test current of 20mA, resulting in a power rating of 48mW. The optical intensity is rated at 100mcd. The lens is colorless, water-clear, and rectangular with a flat top.

Feature Summary

• Compact 0402 surface-mount form factor designed for space-constrained PCB layouts
• High brightness yellow emission with a wide 120-degree viewing angle
• Water-clear rectangular lens providing consistent optical transmission
• RoHS compliant construction suitable for modern environmental standards

Applications

• General electronic equipment status indication
• Battery pack component signaling

• Industrial control system status displays

Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, as the manufacturer offers multiple tape and reel options. Confirm that the selected variant matches the required moisture sensitivity level and reflow soldering profile requirements for the assembly process. Cross-reference the datasheet revision date to ensure compatibility with current design specifications and regulatory compliance standards.

Selection Notes

Select this component when a compact yellow indicator is required for high-density circuit designs. The 0402 footprint allows for automated pick-and-place assembly while maintaining a low profile. Ensure the driving circuit provides the necessary current limiting to maintain the 20mA test condition without exceeding the thermal limits defined in the electrical characteristics table.
