CLM1C-WKW-CWAXB153

Overview

The CLM1C-WKW-CWAXB153 is a Cool White Surface-Mount Device (SMD) LED from the Cree CLM1C series, housed in a standard 2-PLCC package. It features a flat-top lens design optimized for mating with light pipes and customized lighting solutions. The component operates at a typical forward voltage of 3.2V with a test current of 20mA. It provides a wide viewing angle of 120 degrees and is available in cool white color temperatures ranging from 4600K to 15000K, with a typical value of 6800K. Luminous intensity varies by binning, typically spanning 710 to 1800 mcd. The device measures 3.2mm x 2.7mm with a maximum height of 2.05mm.

Feature Summary

• Flat-top package geometry facilitates precise alignment and mating with light pipes for customized optical systems.
• Wide 120-degree viewing angle ensures broad light distribution suitable for general illumination tasks.
• High-intensity light output within an industry-standard PLCC2 footprint for compact design integration.

Applications

• Linear lighting fixtures
• Channel letter signage
• General backlighting applications

Procurement Notes

Verify the specific luminous intensity bin and color temperature coordinate against the manufacturer's datasheet before ordering, as these parameters vary significantly across the CWAXB153 suffix range. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure that the selected variant matches the thermal management capabilities of your target application environment.

Selection Notes

Select this component when a standard PLCC2 footprint is required but higher optical control via light pipe integration is needed due to the flat-top lens profile. Consider the wide viewing angle for applications requiring uniform illumination without secondary optics. Evaluate the specific mcd binning requirements to ensure sufficient brightness for the intended distance and ambient conditions.

Part Context

This part belongs to the Cree XLamp CLM1C family of high-performance PLCC LEDs. The series is designed for reliability in various environmental conditions. The CLM1C form factor serves as a common interface for low-power indicator and illumination needs, bridging the gap between discrete indicators and higher-power array solutions.

Replacement Considerations

Direct substitutes include other PLCC2 white LEDs from manufacturers such as Marktech or Everlight, provided they match the 3.2x2.7mm dimensions and pin configuration. Verify that replacement parts offer comparable forward voltage characteristics and luminous intensity bins to maintain system performance consistency.

FAQ

What is the primary advantage of the flat-top lens on this LED?

The flat-top design allows for easier and more precise mating with light pipes, enabling customized lighting solutions with improved optical efficiency compared to domed lenses.

Does the CLM1C-WKW-CWAXB153 support reverse voltage operation?

No, LEDs are diodes. The absolute maximum ratings specify a reverse voltage limit, exceeding which may damage the component; it is not designed for reverse conduction.
