CLM4B-RKC-CWAXAAA3

Overview

The CLM4B-RKC-CWAXAAA3 is a red surface-mount LED from the CLM4B series, manufactured by Cree LED. It features a PLCC-4 package with a round flat tinted lens and a dominant wavelength of 624nm. The component operates at a forward current of 50mA with a forward voltage of 2.4V. Power ratings vary between 120mW and 210mW across different sources. The device has a height of 1.95mm and is supplied in tape and reel packaging.

Feature Summary

• Single-color red illumination with a round flat lens design
• Surface mount PLCC-4 package for simplified board integration
• Optimized for low-power consumption applications

Applications

• Indicator lights for electronic devices
• Low-power status indication systems
• Consumer electronics front panels

Procurement Notes

Verify the specific suffix (CWAXAAA3 vs CWaXaAA3) against official datasheets to confirm exact power rating and optical characteristics. Ensure compatibility with automated pick-and-place equipment due to the tape and reel packaging format. Confirm RoHS compliance status directly with the manufacturer or authorized distributors before finalizing procurement orders.

Selection Notes

Select this component when a standard red indicator is required in a compact PLCC-4 footprint. Consider the 50mA forward current requirement for driver circuit design. Evaluate the 2.4V forward voltage drop to ensure proper biasing within the target system's power budget. Verify mechanical height constraints against the 1.95mm specification.

Part Context

This part belongs to the CLM4B series of single-color LEDs designed for surface mount technology. It serves as a discrete indicator component, distinct from high-power arrays like the CXA series. The PLCC-4 package provides a standardized form factor widely used in consumer electronics and industrial control panels for visual signaling.

Replacement Considerations

Cross-reference with other Cree LED parts in the CLM4B series for alternative color options or binning specifications. Verify pinout compatibility with existing PCB footprints when substituting similar PLCC-4 packages from other manufacturers.
