CLM3A-WKW-CWAXA453

Overview

The CLM3A-WKW-CWAXA453 is a cool white surface-mount LED from the Cree LED PLCC2 series. It features a rectangular tinted lens and operates within a temperature range of -40°C to +100°C. Key electrical parameters include a forward voltage of 3.2V and a light intensity of 3.6 cd. The device emits at a color temperature of 5500K with a viewing angle of 120 degrees. Physical dimensions are 2.70mm L x 2.00mm W, with a maximum height of 1.3mm to 1.40mm. It utilizes a 2-SMD J-Lead package configuration.

Feature Summary

• Utilizes a PLCC-2 SMD package design for compact surface mounting applications.
• Features a wide 120-degree viewing angle suitable for general illumination needs.
• Constructed with a rectangular tinted lens for directed light output.

Applications

• Channel letter signage
• General backlighting systems
• Panel indicator illumination

Procurement Notes

Verify the specific suffix against official manufacturer documentation to ensure correct binning and optical characteristics. Confirm that the ordering part number matches the required forward voltage and luminous intensity specifications for the target application. Cross-reference datasheet revisions to validate current production status and compliance certifications prior to final procurement decisions.

Selection Notes

Select this component when a low-profile cool white LED is required for space-constrained designs. The PLCC-2 form factor supports automated pick-and-place assembly processes. Ensure the operating temperature range aligns with the environmental conditions of the end product. Consider the 120-degree beam spread for uniformity requirements in direct-view or diffused lighting setups.

Part Context

This model belongs to the Cree LED CLM3A series, which focuses on high-reliability surface-mount indicators. The PLCC2 footprint is a standard industry format compatible with widespread PCB manufacturing equipment. The series offers consistent performance across various industrial and commercial signaling applications requiring discrete LED components.

Replacement Considerations

Direct substitutes may include other PLCC-2 cool white LEDs with matching 2.7x2.0mm dimensions. Verify pin compatibility and forward voltage tolerance before swapping. Alternative models from the same family, such as those with different color temperatures, require thermal and optical re-evaluation.
