CLM4B-RKW-CWAXBAA3

Overview

The CLM4B-RKW-CWAXBAA3 is a single-color surface-mount LED from Cree LED, packaged in a standard PLCC-4 form factor measuring 3.2 mm by 2.7 mm with a height of 1.95 mm. It emits red light at a typical dominant wavelength of 624 nm. The component features a non-diffused round flat lens and operates within a temperature range of -40°C to +100°C. Electrical characteristics include a forward voltage of 2.4 V at a forward current of 50 mA, resulting in a power rating of 210 mW. It delivers a luminous intensity of 2.8 cd with a wide viewing angle of 120 degrees.

Feature Summary

• High-reliability performance designed for diverse environmental conditions
• Flat-top emitting surface facilitates mating with light pipes
• Wide 120-degree viewing angle for broad illumination coverage
• RoHS-compliant and lead-free construction

Applications

• Channel letter lighting
• Architectural lighting
• Light strip applications

Procurement Notes

Verify the specific ordering suffix against official Cree documentation to confirm exact binning parameters, as suffixes define precise optical and electrical tolerances. Ensure compatibility with moisture sensitivity levels and reflow soldering profiles specified in the datasheet. Confirm that the requested package type matches the manufacturing requirements for automated surface-mount assembly processes.

Selection Notes

Select this component for applications requiring high reliability and wide viewing angles in architectural or channel letter contexts. Consider the 120-degree viewing angle and flat-top surface for efficient light pipe coupling. Evaluate the 2.8 cd intensity and 624 nm wavelength against design requirements. Verify thermal management capabilities given the 100°C maximum operating temperature limit.
