B1591UYG-20C000112U1930

Overview

The B1591UYG-20C000112U1930 is a yellow-green surface-mount LED with a 571nm peak wavelength and 2.1V forward voltage. It utilizes a 1206 (3216 metric) package measuring 3.2mm x 1.6mm x 1.85mm. The component features a top-view dome lens design for broad visibility.

Feature Summary

• Top-view configuration with dome lens structure
• Yellow-green emission at 571nm wavelength
• RoHS compliant lead-free construction

Applications

• Discrete status indication in electronic circuits
• Panel mount indicator lights
• General-purpose visual signaling devices

Procurement Notes

Verify the specific suffix 'UYG' to confirm the yellow-green color variant, as Harvatek uses distinct codes for different wavelengths within the B1591 series. Ensure compatibility with standard reflow profiles for 1206 packages. Confirm RoHS compliance status through official manufacturer documentation prior to integration.

Selection Notes

Select this component for applications requiring a compact 1206 footprint with high-brightness yellow-green output. The 2.1V forward voltage suits low-voltage logic interfaces. Consider the dome lens geometry for wide viewing angles compared to flat-top alternatives.

Part Context

This part belongs to the B1591 series of surface-mount LEDs from Harvatek Corporation. The series offers various colors in a standardized 1206 package, providing designers with consistent mechanical dimensions while allowing flexibility in optical characteristics for diverse indicator needs.
