C5SMF-BJE-CR0U0451

Overview

The C5SMF-BJE-CR0U0451 is a single-color blue LED from the Screen Master family, manufactured by Cree LED. It utilizes a T-1 3/4 (5 mm) through-hole package with an oval dome lens measuring 5.1 mm x 3.7 mm. The component emits light at a wavelength of 470 nm with a luminous intensity of 1100 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. It operates within a temperature range of -40°C to +95°C.

Feature Summary

• Features an oval dome lens shape designed for specific radiation patterns.
• Constructed with a water-clear lens material for optimal light transmission.
• Engineered for high luminous intensity suitable for visible signage applications.

Applications

• Variable-message signs
• Passenger-information signs
• Industrial status indicators

Procurement Notes

Verify component availability as this part may be discontinued or subject to supply constraints. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure ordering suffixes match required binning specifications for color and intensity. Check for alternative packages if lead times are critical. Validate pin compatibility with existing PCB footprints.

Selection Notes

Select this component when a wide viewing angle and high brightness are required for direct visibility applications. The 5 mm oval form factor allows for compact mounting while maintaining significant optical output. Consider the 3.4 V forward voltage drop for circuit design efficiency. Evaluate thermal management requirements given the 140 mW power rating and operating temperature limits.

Part Context

This device belongs to the Screen Master series, specifically optimized for outdoor and indoor signage environments. The C5SMF-BJE variant denotes a blue emission with specific lens coloring. It shares mechanical dimensions with other T-1 3/4 LEDs but differs in optical performance and spectral output compared to red or green variants in the same family.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-reference options directly with Cree LED engineering support or authorized distributors for equivalent electrical and mechanical specifications.
