QBLP655-RGB

LED Indication - Discrete Overview

The QBLP655-RGB is a surface-mount RGB LED indicator from the QBLP655 series by QT Brightek. It features a common anode configuration in a 1205 (3.20mm x 1.20mm) package with a clear lens. The component emits red light at 623nm, green at 520nm, and blue at 470nm. Typical forward voltages are 2V for red and 3.1V for green and blue channels. Rated test currents are 20mA per channel, producing luminous intensities of 90mcd (red), 450mcd (green), and 95mcd (blue). It offers a 140° viewing angle and operates within a -40°C to 80°C temperature range.

LED Indication - Discrete Feature Summary

• Integrates red, green, and blue emitters into a single compact surface-mount package
• Provides wide 140-degree viewing angle for broad visibility
• Features a clear square lens with a flat top design
• Supports standard surface mount installation processes

LED Indication - Discrete Applications

• Status indication on electronic circuit boards
• Multi-color visual signaling in consumer devices
• Backlighting applications requiring color mixing
• Indicator lights in portable electronics

LED Indication - Discrete Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to ensure correct binning and optical characteristics. Confirm that the required forward voltage and current ratings align with the target circuit design. Check moisture sensitivity level requirements for storage and reflow soldering compatibility. Ensure the 1205 footprint matches the printed circuit board layout constraints.

LED Indication - Discrete Selection Notes

Select this component when space-constrained designs require multi-color functionality in a single footprint. The common anode structure simplifies driving circuitry compared to discrete LEDs. Consider the significant difference in luminous intensity between the green and red/blue channels when designing optical output expectations. Verify thermal management capabilities if operating near the maximum rated current limits.

LED Indication - Discrete Part Context

This part belongs to the QBLP655 series of chip LEDs manufactured by QT Brightek. The series includes various single-color variants such as red, orange, yellow-green, and white options. These components share similar physical dimensions and mounting characteristics but differ in semiconductor materials and optical outputs. The series is designed for general-purpose indication tasks in modern electronics manufacturing.

LED Indication - Discrete Replacement Considerations

Direct substitutes include other QBLP655-RGB variants from QT Brightek with different packaging or binning codes. Cross-brand replacements must match the 1205 footprint, common anode configuration, and compatible forward voltage ranges. Verify that alternative RGB LEDs provide comparable luminous intensity and viewing angles to maintain design specifications.
