C4SMF-RJF-CT34QBB1

Overview

The C4SMF-RJF-CT34QBB1 is a single-color red LED from the Screen Master series, manufactured by Cree LED. It utilizes a through-hole mounting style within a T-1 3/4 (5 mm) package. The device emits light at a peak wavelength of 624 nm with a forward voltage of 2.1 V at a forward current of 20 mA. It features an oval lens shape and water-clear transparency. The component has a power rating of 130 mW and operates within a temperature range of -40°C to +95°C.

Feature Summary

• Designed specifically for variable-message signs and passenger-information displays
• Features an oval-shaped radiation pattern optimized for wide viewing angles
• Provides high luminous intensity suitable for clear visibility in signage applications

Applications

• Variable-message signs
• Passenger-information signs
• Public transportation display systems

Procurement Notes

Verify the exact suffix configuration against the manufacturer's official datasheet to ensure correct optical and electrical characteristics. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary. Ensure the through-hole package dimensions match the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when designing signage requiring specific red wavelengths around 624 nm. The oval lens geometry supports wide-angle illumination necessary for public information displays. Consider the 2.1 V forward voltage drop for circuit design calculations. Verify thermal management capabilities given the operating temperature limits up to +95°C for outdoor or high-traffic environments.

Part Context

This part belongs to the Screen Master family of LEDs, which are engineered for robust performance in digital signage. The C4SMF series specifically targets the 5 mm through-hole form factor, balancing compact size with high brightness output. These components are standard choices for creating reliable visual indicators in large-scale display matrices used in transit and commercial sectors.

Replacement Considerations

Cross-reference compatible parts such as C5SMF-RJS-CU14QBB1 for similar 5 mm oval red LED specifications. Ensure substitute components maintain identical pin configurations and mechanical dimensions for direct board replacement without redesigning the housing or PCB layout.
