BL-HKB33Q-AV-TRB

Overview

The BL-HKB33Q-AV-TRB is a single-color surface-mount LED manufactured by American Bright Optoelectronics Corporation. It emits yellow light with a peak wavelength of 590 nm and features a water-clear rectangular lens in a standard 1206 (3.2x1.5mm) package. The component operates at a forward voltage of 2.2 V and has a typical luminous intensity of 45 mcd. Designed for low-profile applications, it utilizes AlGaInP/GaAs material technology to provide reliable indication signals in electronic devices.

Feature Summary

• Yellow monochromatic emission with water-clear rectangular lens
• Standard 1206 surface-mount package for low-profile integration
• AlGaInP/GaAs semiconductor material construction

Applications

• Electronic device status indication
• Panel indicator lights
• General-purpose signal signaling

Procurement Notes

Verify the specific datasheet version when sourcing, as manufacturers may update electrical characteristics or mechanical dimensions over time. Confirm that the ordering suffix matches the required tape-and-reel packaging configuration. Ensure compatibility with standard SMT reflow profiles provided in the official reliability guidelines. Cross-reference the manufacturer part number against authorized distributor catalogs to avoid counterfeit components.

Selection Notes

Select this component for applications requiring a compact yellow indicator within a 1206 footprint. Consider the 2.2 V forward voltage drop when designing series resistor networks or constant current drivers. Evaluate the 45 mcd intensity against ambient lighting conditions to ensure visibility requirements are met. Verify that the water-clear lens appearance aligns with the desired aesthetic and optical transmission needs of the final product design.

Part Context

This component belongs to the BL-HKB series of single-color SMD LEDs from American Bright Optoelectronics Corporation. The series utilizes AlGaInP/GaAs materials for red and yellow emissions. The 1206 package size represents a standard industry form factor balancing board space constraints with adequate light output for visible indication purposes in consumer and industrial electronics.

Replacement Considerations

Direct substitutes include other 1206 yellow SMD LEDs with similar forward voltage and intensity ratings. Check mechanical height specifications to ensure fit within the designated PCB cavity. Verify spectral peak wavelength alignment if color matching is critical across multiple units.
