C503B-RBS-CY0Z0AA2

Overview

The C503B-RBS-CY0Z0AA2 is a red light-emitting diode from the Cree LED series, housed in a 5 mm (T-1 3/4) radial through-hole package. It emits at a dominant wavelength of 624 nm with a typical forward voltage of 2.1 V and a maximum power dissipation of 130 mW. The component features a 23-degree viewing angle and offers a luminous intensity range of 3000 to 12000 mcd. Constructed with optical-grade epoxy containing UV inhibitors, it ensures stable light output and resistance to high temperatures and moisture.

Feature Summary

• Advanced optical-grade epoxy encapsulation provides superior resistance to high temperatures and high moisture for outdoor durability.
• Encapsulation resin includes UV inhibitors to minimize degradation effects from long-term direct sunlight exposure.
• Radial lead configuration supports standard through-hole mounting techniques for electronic assemblies.

Applications

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

Procurement Notes

Verify the specific suffix against official Cree documentation to confirm exact luminous intensity binning and wavelength tolerances. Ensure the selected variant matches the required viewing angle and forward voltage specifications for the target circuit design. Cross-reference the RoHS compliance status and moisture sensitivity level before finalizing procurement orders.

Selection Notes

Select this component when high readability in outdoor environments is required due to its UV-stable epoxy construction. The 23-degree beam angle suits applications needing moderate light concentration. Verify that the 2.1 V forward voltage aligns with the driving circuit's current limiting requirements and thermal management strategy for reliable operation.

Part Context

This part belongs to the C503B family of 5-mm round LEDs designed for superior light output in demanding conditions. The RBS designation indicates a red color variant with a 23-degree viewing angle. These lamps are engineered for stability and longevity in harsh environmental conditions where standard indicators might fail.
