C503C-ACN-CYCZA251

Overview

The C503C-ACN-CYCZA251 is a single-color amber LED from the Cree LED family, designed for through-hole mounting in a 5 mm (T-1 3/4) radial package. It features a clear lens and emits light at a dominant wavelength of 591 nm with a typical forward voltage of 2.1 V at a test current of 20 mA. The component offers a luminous intensity range of 3000 to 8200 mcd and a viewing angle of 30 degrees. It operates within a temperature range of -40°C to +95°C and complies with RoHS standards.

Feature Summary

• Utilizes advanced optical-grade epoxy encapsulation for superior high-temperature and high-moisture resistance.
• Incorporates UV inhibitors in the resin to minimize degradation from direct sunlight exposure.
• Provides stable light output over the component's operational life in outdoor environments.

Applications

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

Procurement Notes

Verify the specific suffix against official datasheets to confirm exact luminous intensity binning and wavelength tolerances. Ensure the procurement channel provides valid RoHS compliance documentation. Confirm that the packaging format matches the required manufacturing process, as bulk and tape-and-reel options may vary by distributor.

Selection Notes

Select this component when a 30-degree viewing angle is required for indicator applications. The 5 mm T-1 3/4 form factor ensures compatibility with standard through-hole PCB layouts. Consider the 2.1 V forward voltage drop for circuit design calculations. Verify thermal management requirements if operating near the maximum junction temperature limits specified in the datasheet.
