CLM4B-PKW-CXAXBBB3

Overview

The CLM4B-PKW-CXAXBBB3 is a single-color surface-mount LED from the Cree LED PLCC4 family, designed for high-reliability performance in demanding environments. It features a standard PLCC-4 package with dimensions of 3.2 mm x 2.7 mm and a height of approximately 1.95 mm. The component emits purple light with a typical dominant wavelength of 405 nm. It offers a luminous intensity range of 140 to 355 mcd and operates within a temperature range of -40°C to +100°C. The device supports a forward current of 50 mA and includes a non-diffused, round flat lens.

Feature Summary

• High-reliability construction suitable for wide environmental conditions
• Wide 120-degree viewing angle for broad illumination coverage
• Flat-top emitting surface compatible with light pipe mating
• RoHS-compliant and lead-free manufacturing

Applications

• Channel letter lighting
• Architectural accent lighting
• Light strip integration

Procurement Notes

Verify the specific suffix codes against the official datasheet to confirm wavelength and binning accuracy. Ensure compatibility with standard PLCC-4 footprints during PCB layout. Confirm moisture sensitivity level requirements for storage and reflow soldering processes prior to assembly.

Selection Notes

Select this component when a compact, high-intensity purple source is required for signage or architectural applications. Consider the 120-degree viewing angle for uniform distribution needs. Evaluate thermal management strategies given the maximum operating temperature rating of 100°C for long-term reliability.

Part Context

This part belongs to the Cree LED PLCC4 SMD LED series, which provides standardized packaging for various colors including blue, green, red, amber, and white. The family is engineered for drop-in replacement capabilities in existing designs requiring improved reliability and optical consistency across different color options.

Replacement Considerations

Consult official substitution guides for equivalent PLCC-4 packages from other manufacturers. Verify pinout compatibility and spectral matching if replacing with similar single-color LEDs.
