C5SMF-BJN-CT34Q4T1

Overview

The C5SMF-BJN-CT34Q4T1 is a Screen Master® 5-mm oval LED manufactured by Cree LED. It emits blue light with a peak wavelength of 470 nm and a typical forward voltage of 3.4 V at a test current of 20 mA. The component features a radial through-hole T-1 3/4 (5 mm) package with a clear dome oval lens. Key electrical parameters include a maximum power rating of 140 mW and an operating temperature range from -40 °C to +95 °C.

Feature Summary

• Designed for variable-message signs and passenger-information displays
• Oval-shaped radiation pattern ensures wide viewing angles
• High luminous intensity suitable for public information signage

Applications

• Variable-message signs
• Passenger-information signs
• Public display indicators

Procurement Notes

Verify the specific suffix CT34Q4T1 against official Cree documentation to confirm binning, packaging type, and compliance status. Ensure compatibility with existing board layouts and thermal management requirements before procurement.

Selection Notes

Select this component for applications requiring high-intensity blue illumination in a standard 5-mm oval form factor. Consider the 3.4 V forward voltage drop when designing drive circuits and ensure the operating environment stays within the specified temperature limits.

Part Context

This part belongs to the Screen Master® family of LEDs, which are engineered specifically for outdoor and high-brightness indoor signage applications. The oval shape provides distinct optical characteristics compared to round LEDs, optimizing visibility for text-based displays.

Replacement Considerations

Check for direct substitutes within the C5SMF series with matching wavelength and package dimensions. Verify that any replacement maintains the same forward voltage and luminous intensity requirements for the specific signage application.
