C566C-GFF-CY0Z0781

Overview

The C566C-GFF-CY0Z0781 is a single-color green LED from the Screen Master family, designed for through-hole mounting. It features an oval lens with dimensions of 5.2 mm x 4.6 mm and a height of 7.8 mm. The device operates at a forward current of 20 mA with a forward voltage of 3.4 V. It emits light at a wavelength of 527 nm with a typical luminous intensity of 5200 mcd. The viewing angles are 70 degrees horizontally and 35 degrees vertically. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Oval-shaped radiation pattern optimized for variable-message signs
• Advanced optical-grade epoxy for high-temperature resistance
• Enhanced reliability in outdoor signal applications

Applications

• Variable-message signs
• Passenger-information signs
• Transportation signage

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package integrity and lead time availability through authorized distributors. Ensure compliance with RoHS requirements and handle components according to moisture sensitivity levels specified in the product documentation.

Selection Notes

Select this component for applications requiring specific directional lighting characteristics. The oval shape provides distinct horizontal and vertical beam angles suitable for legibility in signage. Consider the operating temperature range and forward voltage drop when designing driver circuits for consistent performance across environmental conditions.

Part Context

This part belongs to the Cree LED Screen Master series, which includes various single-color LEDs tailored for high-brightness signage. The C566C series utilizes a 5-mm T-1 3/4 package style, offering drop-in compatibility with competing oval LED designs while providing enhanced protection due to its taller lens structure.
