CLM1B-BKW-CTAUB363

Overview

The CLM1B-BKW-CTAUB363 is a single-color blue surface-mount LED from Cree LED, packaged in a PLCC-2 form factor. It emits light at a dominant wavelength of 470 nm with a forward current rating of 20 mA and a forward voltage of 3.1 V. The device features a non-diffused, colorless lens with a rectangular shape and offers a luminous intensity range of 355 to 900 mcd. Rated for operation between -40°C and +100°C, it complies with RoHS standards and is available in reel or cut-tape packaging.

Feature Summary

• High-reliability performance designed for wide environmental conditions
• Flat-top emitting surface facilitates mating with light pipes
• Wide viewing angle suitable for channel letter applications

Applications

• Architectural lighting
• Channel letter signage
• Light strips

Procurement Notes

Verify the specific suffix CTBVA463 against CTAUB363 when sourcing, as Cree uses complex alphanumeric codes to denote binning, packaging, and tape/reel specifications. Confirm moisture sensitivity level (MSL) and reflow soldering profile requirements prior to assembly. Ensure the supplier provides official datasheets matching the exact part number to guarantee correct wavelength and intensity binning for your design.

Selection Notes

Select this component for applications requiring high-brightness blue illumination in standard SMD footprints. The PLCC-2 package allows for easy integration into existing designs using industry-standard mounting techniques. Consider the 120-degree viewing angle for broad distribution needs and verify thermal management capabilities given the power rating constraints of the small form factor.

Part Context

This component belongs to the Cree XLamp CLM series, which are industry-standard PLCC-style LEDs known for reliability. The CLM1B variant specifically denotes the blue color option within this family, sharing physical dimensions and electrical characteristics with other colors like green (CLM1B-GKW). These parts are widely used in indicator and general lighting applications due to their standardized footprint.

Replacement Considerations

Direct substitutes include other PLCC-2 blue LEDs such as the CLM1B-GKW for green variants if color flexibility is needed, or generic equivalents from manufacturers like Kingbright or Everlight that match the 3.2 x 2.7 mm footprint and 3.1V forward voltage. Always verify pinout compatibility and spectral peak alignment before swapping.
