Description

Product Details

 

Cree LED CLM1B-AKW-CUbVb353 High-Intensity Amber PLCC2 SMD for Signaling and Signage. The Cree LED CLM1B-AKW series is a professional-grade amber SMD LED engineered for applications that demand high radiant intensity and long-term environmental stability. Housed in the industry-standard PLCC2 package, the CLM1B-AKW-CUbVb353 is the primary choice for manufacturers of transportation indicators, architectural accent modules, and commercial channel letters. Built on a stable AlGaInP chip platform, this component ensures that the amber spectrum remains consistent throughout its operational life, preventing the wavelength shift issues often associated with budget emitters.
For LED module manufacturers and contract manufacturers (EMS), the CLM1B-AKW offers a low-risk, high-yield solution for automated SMT lines. Its robust lead-frame architecture and tight intensity binning allow fixture manufacturers to produce large-scale displays and signage with zero visible color or brightness variance between individual units.

Critical Engineering Advantages for Manufacturers

 

▶ Precise Amber Spectrum (591nm): Binned at a dominant wavelength of 584nm to 596nm, this LED provides the high-saturation amber light required for international safety signaling and transportation compliance.
▶ Optimized PLCC2 Thermal Path: The 3.2 x 2.8 mm package is designed for efficient heat transfer from the junction to the solder point. This thermal efficiency minimizes internal stress, protecting the chip and maintaining brightness stability during continuous industrial operation.
▶ Industrial-Grade Reliability: Utilizing high-quality resin materials with integrated UV inhibitors, the CLM1B series resists yellowing and moisture ingress, ensuring an excellent L70 lifespan for 50,000+ hour municipal and commercial projects.
▶ Wide Viewing Angle for Uniformity: The 120-degree viewing angle eliminates "hot spots" in shallow signage boxes and edge-lit panels, providing a perfectly smooth light distribution across the diffusion surface.

FAQ

Q: Can I drive the CLM1B-AKW at its maximum current of 50mA?

A: While it is rated for 50mA, for industrial-grade L70 lifespan maintenance (50,000+ hours), we recommend a nominal drive current of 20mA. If driving higher, proper PCB thermal management (increased copper mass) is essential to manage the AlGaInP chip's heat.

Q: Is the PLCC2 footprint compatible with existing PLCC4 designs?

A: No, the pad layout for PLCC2 (2 leads) is different from PLCC4. However, the external dimensions (3.2x2.8mm) are similar. We recommend checking your PCB layout for specific pad orientation.

Q: How does Gainer LED handle MSL 5a storage?

A: All MSL 5a components are stored in climate-controlled environments and shipped in original vacuum-sealed moisture-barrier bags (MBB) with desiccant and a humidity indicator card.

Q: Does Gainer LED provide samples for color-matching?

A: Yes, we support LED module manufacturers with sample quantities for R&D evaluation and wavelength-matching tests before full-scale wholesale orders are placed.
