BL-HG034E-TRB

Overview

The BL-HG034E-TRB is a surface mount green LED from American Bright Optoelectronics Corporation. It utilizes an 0802 (2125 metric) package with dimensions of 2.1mm x 1.25mm. The component emits green light with a typical forward voltage of 2.2V and a millicandela rating of 10mcd. The lens features a round, domed top style with a 1.70mm diameter and clear transparency. Designed for SMD/SMT installation, it serves as a discrete indicator source in electronic assemblies requiring compact form factors.

Feature Summary

• Compact 0802 surface mount package design
• Green emission with domed lens structure
• Clear lens transparency for optimal visibility

Applications

• Panel status indicators
• Board activity signaling
• Consumer electronics status lights

Procurement Notes

Verify the exact datasheet version before integration, as specifications may vary between manufacturing batches. Confirm that the 0802 footprint matches your PCB layout constraints. Ensure compatibility with standard reflow soldering profiles for SMD components. Cross-reference the 10mcd brightness requirement against ambient lighting conditions to guarantee adequate visibility in the final application environment.

Selection Notes

Select this component when space constraints necessitate an 0802 footprint rather than larger packages like 0603 or 0805. The 2.2V forward voltage aligns with standard low-voltage logic levels. Consider the 10mcd output sufficient for direct line-of-sight indication but potentially insufficient for high-glare environments without optical assistance. The domed lens aids in light diffusion compared to flat top variants.

Part Context

This part belongs to the American Bright Optoelectronics Corporation discrete LED portfolio. It represents a standard green indicator solution within their SMD lineup. The manufacturer offers various other colors and package sizes, allowing for consistent sourcing across different product lines. This specific model focuses on balancing size reduction with adequate luminous intensity for general purpose use.

Replacement Considerations

Direct substitutes include other 0802 green LEDs from manufacturers like Kingbright or Everlight, provided pinout and electrical characteristics match. Verify that alternative parts maintain the same 2.2V forward voltage tolerance. Check if competing domed lens designs offer comparable viewing angles. Ensure the replacement supports the same moisture sensitivity level for storage and handling.
