C503B-AAS-CZ0A0342

Overview

The C503B-AAS-CZ0A0342 is a Cree LED amber round light-emitting diode designed for high-brightness applications. It features a 5 mm (T-1 3/4) through-hole package with a clear, domed lens and emits at a dominant wavelength of 591 nm. The component operates with a forward voltage of 2.1 V and a maximum forward current of 20 mA, dissipating up to 120 mW. It provides a luminous intensity range of 5860 to 23500 mcd with a narrow 15-degree viewing angle, ensuring excellent readability in outdoor environments.

Feature Summary

• Advanced optical-grade epoxy encapsulation provides superior resistance to high temperatures and moisture for reliable outdoor performance.
• Encapsulation resin includes UV inhibitors to minimize degradation from direct sunlight exposure, maintaining stable light output over the product lifecycle.
• Narrow 15-degree beam angle concentrates light intensity for enhanced visibility in long-range signaling applications.

Applications

• Electronic Signs & Signals (ESS)
• Motorway Signs
• Variable-Message Sign (VMS)

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure compatibility with required intensity and wavelength specifications. Confirm RoHS compliance status prior to integration. Check manufacturing availability as distribution channels may list varying stock levels or end-of-life statuses for this component series.

Selection Notes

Select this model when a narrow 15-degree viewing angle is required for focused illumination in transport signage. Ensure circuit design accommodates the 2.1 V forward voltage and 20 mA maximum forward current limits. Consider the 5 mm T-1 3/4 package dimensions for PCB layout and mechanical mounting constraints in outdoor enclosures.

Part Context

This component belongs to the Cree C503B family of 5-mm round LEDs, specifically engineered for red and amber color options. The AAS designation indicates the 15-degree viewing angle variant within this series. These lamps are optimized for global transport signage markets requiring high brightness and environmental durability.
