CLM4B-BKB-CUBVA453

Overview

The CLM4B-BKB-CUBVA453 is a surface-mount LED from Cree's PLCC4 family, featuring a blue emission with a typical dominant wavelength of 470 nm. Packaged in the industry-standard 3.2 x 2.7 mm PLCC4 footprint, it operates at a forward voltage of 3.1 V and a forward current of 35 mA. The device offers a wide 120-degree viewing angle and utilizes a flat-top emitting surface to facilitate mating with light pipes. It is RoHS-compliant and lead-free, designed for high reliability under various environmental conditions.

Feature Summary

• Industry-standard PLCC4 package size for easy integration
• Wide 120-degree viewing angle for broad illumination coverage
• Flat-top emitting surface compatible with light pipe applications
• High-reliability performance suitable for demanding environments

Applications

• Channel letter lighting
• Architectural lighting
• Light strip illumination
• General backlighting

Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm electrical characteristics and binning requirements. Ensure compliance with RoHS standards and lead-free specifications as documented. Cross-reference the part number with official distributor catalogs to validate availability and authenticity before procurement.

Selection Notes

Select this component for applications requiring a standard SMD footprint with wide-angle blue illumination. Consider the 3.1 V forward voltage and 35 mA operating current for driver design. The flat-top surface is advantageous when coupling with optical elements like light pipes. Verify thermal management requirements based on the absolute maximum ratings provided in the technical documentation.

Part Context

This part belongs to the Cree PLCC4 1-in-1 SMD LED series, which includes variants such as CLM4B-GKW for green emission. The series is characterized by its compact 3.2 x 2.7 mm package and high reliability. It is distinct from through-hole LEDs or larger array packages, focusing on discrete indication and general illumination within a standardized form factor.

Replacement Considerations

Direct substitutes include other PLCC4 blue LEDs from different manufacturers if pinout and dimensions match. Verify forward voltage and luminous intensity ranges to ensure functional equivalence. Check for identical package dimensions and thermal characteristics to maintain board layout integrity.
