C503B-RCS-CYAZAAA1-030

Overview

The C503B-RCS-CYAZAAA1-030 is a single-color amber LED from the Cree LED C503B series. It features a 5 mm (T-1 3/4) round package with a clear lens and two pins for through-hole mounting. The device emits light at a dominant wavelength of 624 nm with a luminous intensity range of 3,000 to 12,000 mcd. Key electrical parameters include a maximum forward current of 50 mA, a forward voltage of 2.1 V, and a power dissipation rating of 130 mW. It operates within a temperature range of -40°C to +95°C.

Feature Summary

• Constructed with advanced optical-grade epoxy resin containing UV inhibitors for superior high-temperature and moisture resistance.
• Provides stable light output over the component's life despite long-term exposure to direct sunlight.
• Designed with a 30-degree viewing angle to ensure excellent readability in outdoor environments.

Applications

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

Procurement Notes

Verify the specific suffix codes against the official datasheet to confirm exact luminous intensity binning and wavelength specifications. Ensure that the selected variant matches the required forward current and voltage ratings for the target circuit design. Confirm RoHS compliance status and check for any end-of-life notices or recommended new designations before finalizing procurement plans.

Selection Notes

Select this component when high visibility and durability are required for outdoor signage applications. The amber color and 30-degree beam provide optimal contrast and readability. Consider the thermal management requirements given the 130 mW power dissipation limit. Verify that the through-hole mounting style fits the PCB layout constraints and mechanical assembly process.

Part Context
