CLM4B-RKW-CWBXBAA3

Overview

The CLM4B-RKW-CWBXBAA3 is a single-color red LED from Cree LED, designed for surface-mount installation in PLCC-4 packages. It emits light at a dominant wavelength of 624 nm with a non-diffused round flat lens. Key electrical parameters include a forward current rating of 50 mA and a forward voltage of 2.4 V, resulting in a power rating of 210 mW. The device provides a luminous intensity of 2.8 cd and features a 120-degree viewing angle. Physical dimensions are 3.2 mm in length, 2.7 mm in width, and 1.95 mm in height. It operates within a temperature range of -40 C to +100 C.

Feature Summary

• Surface-mount design in a compact PLCC-4 package for automated assembly
• High luminous intensity output suitable for visible indication applications
• Wide operating temperature range supporting diverse environmental conditions

Applications

• Channel letter signage
• Architectural lighting
• General indicator lamps

Procurement Notes

Verify the specific ordering suffix against official Cree LED documentation to ensure correct binning and optical characteristics. Confirm RoHS compliance status through manufacturer datasheets prior to integration. Check for moisture sensitivity handling requirements during storage and reflow processes. Ensure component availability aligns with production schedules as supply levels may fluctuate.

Selection Notes

Select this component when high brightness red indication is required in space-constrained designs. The PLCC-4 form factor allows for standard SMD placement on PCBs. Consider the 120-degree viewing angle for broad visibility needs. Evaluate thermal management capabilities given the 100 C maximum operating limit. Compare against similar Cree LED models for alternative color or intensity options if specifications do not fully match project requirements.

Part Context

This part belongs to the CLM4B series of single-color LEDs manufactured by Cree LED. The series includes variants in red and amber colors, optimized for channel letter and architectural lighting applications. These components are characterized by lead-free construction and high reliability standards typical of Cree's standard LED portfolio.
