CLM1B-AKB-CUBVB343

Overview

The CLM1B-AKB-CUBVB343 is a single-color surface-mount LED manufactured by Cree LED, classified under discrete indicator LEDs. It features an amber lens with a primary wavelength of 590nm and a typical forward voltage of 2.1V at a test current of 20mA. The component utilizes a 2-PLCC package with dimensions of 3.20mm in length and 2.80mm in width, reaching a maximum height of 2.05mm. It emits an intensity of 560mcd through a rectangular lens with a flat top design. The device operates within a temperature range of -40°C to +100°C and holds RoHS3 compliance.

Feature Summary

• Amber illumination with a 590nm peak wavelength for clear visual signaling
• Compact 2-PLCC surface-mount footprint suitable for space-constrained PCB layouts
• High brightness output of 560mcd ensuring visibility in various lighting conditions
• Robust thermal performance supporting operation up to 100°C

Applications

• Status indication on electronic control panels and user interfaces
• Visual signaling in industrial machinery and automation equipment
• Power status indicators in consumer electronics and appliances
• Signal lights in automotive dashboard and instrument cluster assemblies

Procurement Notes

Verify the specific suffix CUBVB343 against official Cree LED documentation to confirm exact binning and optical characteristics. Ensure compatibility with standard SMT reflow profiles and check moisture sensitivity level (MSL 5A) handling requirements during storage and assembly. Confirm that the 2-PLCC package matches the intended PCB land pattern dimensions.

Selection Notes

Select this component when an amber indicator with moderate brightness is required in a low-profile surface-mount form factor. Consider the 2.1V forward voltage drop for circuit design and ensure the 20mA test current aligns with available drive capabilities. Evaluate the 120-degree viewing angle if wide-angle visibility is necessary for the application environment.

Part Context

This part belongs to the CLM1B series of single-color LEDs from Cree LED, designed for general-purpose indicator applications. The series offers various color options and packaging styles to support diverse design needs. The CLM1B-AKB variant specifically targets amber light emission, providing a reliable solution for status indication in compact electronic devices requiring standardized surface-mount components.
