11450

Overview

SparkFun COM-11450 is a 5mm radial LED component featuring an integrated cycling RGB driver. It emits red, green, and blue light in a slow sequential pattern without requiring external microcontroller logic or complex circuitry. The device operates at a forward voltage of 4.5V and utilizes a standard radial leaded package for through-hole mounting. This accessory simplifies visual signaling by providing automated color transitions directly from the component.

Feature Summary

• Integrated cycling RGB driver eliminates need for external control logic
• Slow sequential color transition between red, green, and blue states
• Standard 5mm radial package facilitates easy through-hole integration

Applications

• Visual status indicators for electronic prototypes
• Decorative lighting in hobbyist electronics projects
• Simple signal generation in educational STEM kits

Procurement Notes

Verify the specific part number COM-11450 against official SparkFun documentation to confirm the integrated cycling functionality and 4.5V operating voltage. Ensure compatibility with your circuit's power supply requirements before procurement. Cross-reference datasheets to validate the radial package dimensions and lead configuration for accurate PCB footprint design.

Selection Notes

Select this component when a simple, self-contained visual indicator is required without programming overhead. It is suitable for applications needing basic color cycling rather than precise color mixing or rapid flashing. Consider the 4.5V forward voltage drop when designing the current-limiting resistor network to ensure proper brightness and longevity.

Part Context

This component belongs to the SparkFun Accessories category, specifically within optoelectronics and discrete LEDs. It serves as a specialized variant of standard RGB LEDs by incorporating internal timing circuits. The product is designed for ease of use in rapid prototyping environments where minimal external components are preferred.

Replacement Considerations

Direct substitutes must feature an integrated cycling driver and similar 5mm radial form factor. Standard addressable RGB LEDs require different control schemes and may not be direct replacements. Verify that any alternative maintains the slow cycling speed and 4.5V operating characteristics.
