C4SMF-BJF-CS24Q3S1

Overview

The C4SMF-BJF-CS24Q3S1 is a blue light-emitting diode from the Screen Master series, manufactured by Cree LED. It features a 4 mm through-hole radial package with an oval lens shape and domed top. The component operates at a forward voltage of 3.4 V typical and emits light at a peak wavelength of 475 nm. It delivers a luminous intensity of 1134 mcd when tested at 20 mA. The device is designed for high-brightness applications requiring wide viewing angles.

Feature Summary

• Oval-shaped radiation pattern engineered for wide-field-of-view performance
• High luminous intensity suitable for variable-message sign applications
• Through-hole mounting configuration for standard PCB integration

Applications

• Variable-message signs
• Wide-field-of-view outdoor indicator lighting
• Uni-color blue accent lighting

Procurement Notes

Verify the specific suffix CS24Q3S1 against the manufacturer's current datasheet to ensure compatibility with required forward voltage and intensity specifications. Confirm that the radial through-hole package dimensions align with the target PCB footprint. Check for any recent product change notifications or end-of-life status updates directly from Cree LED before finalizing procurement plans.

Selection Notes

Select this component when a wide viewing angle and high brightness are critical for visibility in ambient light conditions. The 475 nm blue emission provides distinct color indication compared to standard red or green LEDs. Ensure the circuit design accommodates the 3.4 V forward voltage drop and limits current to 20 mA to maintain optimal lifespan and performance without exceeding thermal ratings.

Part Context

This part belongs to the Screen Master family of LEDs, which are specifically optimized for large-format display and signage applications. The C4SMF series utilizes advanced packaging techniques to enhance light extraction efficiency. As a discrete component, it serves as a fundamental building block for custom lighting solutions requiring precise color and intensity control in commercial environments.

Replacement Considerations

Direct substitutes must match the 4 mm oval through-hole form factor and 475 nm blue wavelength. Verify equivalent forward voltage and luminous intensity ratings to ensure consistent visual output. Cross-reference with other Screen Master variants if higher intensity or different lens styles are acceptable for the application.
