C503B-AAS-CY0Z0341

Overview

The C503B-AAS-CY0Z0341 is a single-color amber LED from the Cree C503B series, designed for through-hole mounting in a 5 mm round package. It features a clear lens and emits at a dominant wavelength of 591 nm with a luminous intensity range of 5860 to 23500 mcd. The component operates with a forward voltage of 2.1 V and a maximum continuous forward current of 20 mA. It offers a narrow 15-degree viewing angle and complies with RoHS standards.

Feature Summary

• Advanced optical-grade epoxy encapsulation provides superior resistance to high temperatures and moisture for outdoor durability.
• Encapsulation resin includes UV inhibitors to minimize degradation from direct sunlight exposure, ensuring stable light output over the LED's life.
• Narrow 15-degree beam angle concentrates light for enhanced readability in electronic signs and signals.

Applications

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

Procurement Notes

Verify the specific suffix against the manufacturer datasheet to confirm exact binning and optical characteristics. Check current lifecycle status as some variants may be discontinued or subject to product change notifications. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement orders.

Selection Notes

Select this component when high-intensity amber illumination with a narrow beam profile is required for long-distance visibility. The 5 mm through-hole format suits legacy designs or applications requiring robust mechanical mounting. Consider the 20 mA current rating for power budget calculations and ensure the operating environment does not exceed the specified temperature limits for the epoxy encapsulation.

Part Context

This part belongs to the C503B family of 5 mm round LEDs, which are engineered for high-performance outdoor signage. The AAS designation indicates an amber color variant with a 15-degree viewing angle. These LEDs utilize advanced materials to withstand harsh environmental conditions while maintaining consistent photometric performance over extended operational periods.
