Overview

The SparkFun COM-07844 is a common-anode RGB LED component featuring red, green, and blue emitters in a 4-SMD no-lead package. The device operates with a forward voltage of 2V for the red channel and 3.5V for both green and blue channels. It utilizes a rectangular lens with a flat top design to achieve a 120-degree viewing angle. Luminous intensity ratings are specified at 81mcd for red, 130mcd for green, and 54mcd for blue. Peak wavelengths are recorded at 621nm for red, 525nm for green, and 475nm for blue.

Feature Summary

Integrates red, green, and blue light sources within a single surface-mount package
Features a rectangular lens with a flat top geometry for directional light emission
Supports mixed-color output through independent control of individual color channels

Applications

Visual status indication in electronic circuits
Decorative lighting modules
RGB backlighting systems

Procurement Notes

Verify the specific manufacturer part number against official distributor catalogs to ensure compatibility with the intended application. Confirm that the common-anode configuration aligns with the circuit design requirements. Review the datasheet for thermal management guidelines and soldering profiles suitable for the 4-SMD no-lead package type.

Selection Notes

Select this component when a compact, multi-color indicator is required for space-constrained designs. Ensure the driving circuitry can handle the distinct forward voltage differences between the red and blue/green channels. Consider the luminous intensity specifications to determine if additional amplification or optical components are necessary for visibility in the target environment.

Part Context

This component belongs to SparkFun's collection of discrete optoelectronic devices designed for prototyping and educational projects. It provides a convenient solution for creating colored signals without requiring multiple separate LED packages. The standardized SMD footprint facilitates easy integration into custom PCB layouts for hobbyist and professional development boards.
