C503B-GCS-CA0B0782

Overview

The C503B-GCS-CA0B0782 is a single-color green LED from the Cree LED C503B series. It features a T-1 3/4 (5 mm) round package with a clear dome lens and through-hole mounting. The device emits at a dominant wavelength of 527 nm with a viewing angle of 30 degrees. Electrical characteristics include a forward voltage of 3.2 V and a forward current of 20 mA, resulting in a power rating of 120 mW. Luminous intensity ranges from 5860 to 32900 mcd. Operating temperature spans from -40 °C to +95 °C.

Feature Summary

• Advanced optical-grade epoxy encapsulation for high-temperature and moisture resistance
• UV inhibitors integrated into the resin to minimize sunlight degradation effects
• Stable light output maintained over long operational periods
• Superior light output designed for excellent readability in direct sunlight

Applications

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

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number with official datasheets. Confirm RoHS compliance status and check for specific packaging variations such as Ammo Pack or Bulk. Ensure the supplier provides valid traceability documentation. Validate that the received units match the specified 527 nm wavelength and 30-degree viewing angle parameters before integration.

Selection Notes

Select this component for applications requiring high visibility in outdoor environments due to its sunlight-readable design. The 30-degree viewing angle offers a wider beam compared to narrow-angle variants. Consider the 5 mm radial leaded package for standard through-hole PCB layouts. Evaluate the thermal management requirements given the 95 °C maximum operating temperature limit.

Part Context

This component belongs to the C503B family of 5-mm round LEDs manufactured by Cree LED. The series includes red, amber, blue, and green variants with different viewing angles (15, 23, and 30 degrees). These LEDs are engineered for robust performance in harsh outdoor conditions, utilizing specialized epoxy materials to ensure longevity and consistent optical output.
