C5SMF-BJF-CT34Q3T2

Overview

The C5SMF-BJF-CT34Q3T2 is a single-color blue LED from the Cree Screen Master series, designed for through-hole mounting in a T-1 3/4 (5 mm) oval package. It features a dominant wavelength of 470 nm and emits blue illumination with a luminous intensity of 1310 mcd. The component operates at a forward current of 20 mA with a forward voltage of 3.4 V and a power rating of 140 mW. It has an oval lens measuring 5.1 mm x 3.7 mm with a viewing angle of 100 degrees by 40 degrees. The device functions within a temperature range of -40°C to +95°C.

Feature Summary

• Engineered specifically for variable-message signs and passenger-information displays
• Features an oval-shaped radiation pattern for directional light distribution
• Provides high-intensity blue illumination suitable for clear visibility applications

Applications

• Variable-message signs
• Passenger-information signs
• Retail lighting environments requiring precise color control

Procurement Notes

Verify the specific suffix CT34Q3T2 against official Cree documentation to confirm exact binning and optical characteristics. Confirm availability status as distribution channels may list obsolete or out-of-stock items. Ensure the ordering part number matches the required electrical and mechanical specifications before purchase.

Selection Notes

Select this component when an oval beam profile is required for signage applications. Compare the 1310 mcd intensity and 470 nm wavelength against project requirements. Consider the T-1 3/4 package dimensions for PCB layout compatibility. Verify thermal management capabilities given the 140 mW power rating.

Part Context

This part belongs to the C5SMF family of Screen Master LEDs, which are optimized for large-format display applications. The CJF/BJF/RJF variants offer different colors within the same oval form factor. This specific model provides blue light output tailored for high-visibility information displays.

Replacement Considerations

Check for C5SMF-BJF-CR14Q3T2 or other C5SMF-BJF variants with different suffixes if binning differences are acceptable. Verify that substitute parts maintain the same 5 mm oval package and electrical parameters.
