CLM3C-WKW-CXAYA453

Overview

The CLM3C-WKW-CXAYA453 is a single-color cool white surface-mount LED from the Cree LED CLM3C series. It utilizes a PLCC-2 package with dimensions of 2.70mm length, 2.00mm width, and a maximum height of 1.3mm to 1.40mm. The component emits light at a color temperature of 5500K with a viewing angle of 120 degrees. Electrical characteristics include a typical forward voltage of 3.2V to 4V and a test current of 20mA. Optical performance varies by source, citing luminous intensities ranging from 1.8 cd to 3.6 cd, with a power rating of 100mW. The lens features a rectangular shape with a flat top and diffused transparency.

Feature Summary

• Compact PLCC-2 surface mount design for space-constrained applications
• Cool white emission optimized for indicator and status signaling
• High reliability construction suitable for diverse environmental conditions

Applications

• Electronic device status indicators
• Power supply unit signal lights
• Control panel illumination

Procurement Notes

Verify the specific optical intensity grade required for the application, as datasheets cite varying candela values (1.8 cd to 3.6 cd) for this part number. Confirm the exact forward voltage specification (3.2V vs 4V) against the manufacturer's latest official datasheet to ensure circuit compatibility. Ensure compliance with RoHS3 standards and check Moisture Sensitivity Level (MSL) 5A handling requirements during assembly.

Selection Notes

Select this component when a standard PLCC-2 footprint is required for cool white indication. Consider the 120-degree viewing angle for visibility requirements. Evaluate the thermal management needs based on the 100mW power rating. Compare against other CLM3C variants if different color temperatures or binning specifications are necessary for the final product design.

Part Context

This component belongs to the Cree LED CLM3C family, which offers high-reliability SMD LEDs in an industry-standard PLCC-2 package. The series is designed for general-purpose lighting and indication tasks. The CLM3C-WKW suffix specifically denotes the cool white color variant within this lineup, sharing common mechanical dimensions and electrical interface characteristics with other colors in the same series.

Replacement Considerations

Direct substitutes within the same series include CLM3C-WKW-CWBYA153, which shares the PLCC-2 package and cool white emission but may differ in optical intensity binning. Verify pinout compatibility and dimensional tolerances before substitution.
