CLM1C-WKW-CXAXB153

Overview

The CLM1C-WKW-CXAXB153 is a cool white surface-mount LED from Cree LED, housed in an industry-standard PLCC-2 package. It operates at a forward voltage of 3.1 V with a test current of 20 mA. The component emits light at a color temperature of 6800 K and provides a luminous intensity of 2.1 cd (2100 mcd). It features a round lens with a flat top design and offers a wide viewing angle of 120 degrees. Physical dimensions are 3.2 mm in length, 2.7 mm in width, and 1.95 mm in height.

Feature Summary

• Flat-top lens design facilitates mating with light pipes for customized lighting solutions
• High-intensity light output within an industry-standard PLCC-2 package
• Wide 120-degree viewing angle for broad illumination coverage

Applications

• Light strips
• Channel letters
• Backlighting

Procurement Notes

Verify the specific binning code suffix to ensure the correct color temperature and luminous intensity match your design requirements. Confirm that the PLCC-2 footprint aligns with your PCB layout. Check RoHS compliance status if required by your manufacturing standards. Ensure thermal management considerations are addressed for sustained operation.

Selection Notes

Select this component when a standard SMD form factor with high brightness is required. The 6800K color temperature suits applications needing cool white illumination. Consider the 3.1V forward voltage drop for power supply calculations. The flat-top profile is advantageous for optical coupling with light guides or diffusers.

Part Context

This part belongs to the Cree CLM1 series of white LEDs. The series is characterized by high reliability and suitability for various environmental conditions. The CLM1C variant specifically denotes the cool white color temperature range within the product line.

Replacement Considerations

Cross-reference with other PLCC-2 white LEDs from manufacturers like Marktech or Osram if sourcing constraints exist. Verify pinout compatibility and dimensional tolerances before substitution. Ensure equivalent luminous intensity and color consistency metrics are met.
