CLM4B-AKC-CWBXB353

Overview

The CLM4B-AKC-CWBXB353 is a single-color surface-mount LED manufactured by Cree LED, housed in an industry-standard PLCC-4 package. The component measures 3.2 mm in length and 2.7 mm in width with a maximum height of 1.95 mm. It emits amber light with a typical dominant wavelength of 591 nm. The device features a luminous intensity range of 1120 to 2800 mcd and a viewing angle of 120 degrees. Electrical characteristics include a forward voltage of approximately 2.1 V at a test current of 20 mA, with a maximum operating temperature of +100 °C and a minimum of -40 °C.

Feature Summary

• High-reliability performance designed for wide environmental conditions
• Flat-top emitting surface facilitates mating with light pipes
• Wide 120-degree viewing angle suitable for architectural applications

Applications

• Channel Letter Lighting
• Architectural Lighting
• Light Strip Applications

Procurement Notes

Verify the specific suffix codes against official Cree documentation to confirm exact binning parameters, lens clarity, and packaging configuration. Ensure compatibility with RoHS compliance standards required for the target assembly process. Cross-reference the part number with authorized distributors to validate authenticity and current manufacturing status before procurement.

Selection Notes

Select this component when a standard PLCC-4 footprint is required for high-intensity amber signaling or illumination. The 120-degree viewing angle makes it suitable for applications requiring broad light distribution. Consider the flat-top lens design if integration with optical light pipes is necessary for the specific enclosure geometry.

Part Context

This part belongs to the CLM4B series of SMD LEDs from Cree LED. The series is characterized by its compact PLCC-4 form factor and robust construction for demanding environments. It serves as a specialized solution for visible indication and low-power lighting tasks where standard package dimensions are mandated by existing board layouts.

Replacement Considerations

Direct substitutes within the same PLCC-4 family may include other color variants such as CLM4B-RKW or CLM4B-GKW, provided the spectral output requirements differ. Verify mechanical compatibility and electrical ratings before swapping between different colors or intensities within the series.
