C4SMA-BGF-CR44Q3C2

Overview

The C4SMA-BGF-CR44Q3C2 is a single-color blue LED from the Screen Master series, manufactured by Cree LED. It features an oval dome lens with dimensions of 4 mm x 3 mm and a height of 7.3 mm. The component operates at a peak wavelength of 475 nm and delivers a light intensity of 960 mcd. Electrical characteristics include a forward voltage of 3.4 V and a forward current rating of 20 mA, resulting in a power rating of 140 mW. The lens color is blue with clear transparency, designed for through-hole mounting.

Feature Summary

• High-brightness blue emission optimized for video screen applications
• Oval dome lens design providing wide viewing angles
• Screen Master series classification for consistent performance binning

Applications

• Large-format high-resolution video screens
• Digital advertising signage
• Stadium ribbons and full-color information displays

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lot codes and binning specifications against project requirements. Check for end-of-life status or obsolescence notices prior to procurement. Ensure storage conditions comply with moisture sensitivity levels if applicable. Request detailed test reports for critical optical and electrical parameters.

Selection Notes

Select this component for applications requiring high-intensity blue illumination in outdoor or harsh environments. Consider the 475 nm wavelength for specific color rendering needs. Evaluate thermal management requirements given the 140 mW power rating. Compare luminous intensity against alternative models if higher brightness is necessary. Verify mechanical fit within the target PCB layout due to the oval footprint.

Part Context

This part belongs to the Screen Master family of 4-mm oval LEDs, engineered for demanding visual display tasks. The series is known for reliability in large-scale installations. The C4SMA variant specifically targets blue channel requirements in multi-color LED arrays. It complements other colors in the same package style for uniform pixel pitch construction.

Replacement Considerations

Direct substitutes may include C4SMA-BGF-CR44Q3C1 or C4SMA-BGF-CR34Q3C1, which share similar form factors and electrical profiles. Verify binning compatibility when swapping between suffixes. Alternative packages like C4SMG or C4SMF offer different lens shapes and should be evaluated for mechanical integration.
