C503B-RAS-CY0B0AA1

Overview

The C503B-RAS-CY0B0AA1 is a single-color red LED from the Cree LED series, designed for through-hole mounting in a 5 mm (T-1 3/4) package. It features a round lens with a clear colorless surface and emits light at a dominant wavelength of 624 nm. The component provides a luminous intensity range of 5860 to 23500 mcd with a narrow viewing angle of 15 degrees. Electrical characteristics include a forward voltage of approximately 2.1 V and a maximum power dissipation rating of 120 mW.

Feature Summary

• Advanced optical-grade epoxy encapsulation ensures superior high-temperature and high-moisture resistance suitable for demanding outdoor environments.
• Encapsulation resin contains UV inhibitors to minimize degradation effects from long-term direct sunlight exposure, maintaining stable light output over the product lifecycle.

Applications

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

Procurement Notes

Verify the specific suffix configuration against official manufacturer documentation to ensure correct electrical and optical parameters. Confirm RoHS compliance status and check for any recent Product Change Notifications regarding packaging or material updates before finalizing procurement orders.

Selection Notes

Select this component when a narrow beam spread is required for precise directional indication in signage applications. The 15-degree viewing angle distinguishes it from wider-beam variants within the same 5 mm form factor family, optimizing visibility for specific line-of-sight requirements.

Part Context

This part belongs to the C503B-RAS/RAN/AAS/AAN family of 5-mm round LEDs. These lamps are engineered for excellent readability in outdoor applications, utilizing advanced materials to withstand environmental stressors while delivering consistent performance in signaling roles.
