C566C-RFF-CT0W0BB2

Overview

The C566C-RFF-CT0W0BB2 is a single-color red LED from the Screen Master family, manufactured by Cree LED. It utilizes a T-1 3/4 (5 mm) through-hole package with an oval dome lens measuring 5.2 mm x 4.6 mm. The component emits light at a wavelength of 621 nm with a typical luminous intensity of 2200 mcd. Electrical characteristics include a forward voltage of 2.1 V and a rated forward current of 20 mA, resulting in a power rating of 130 mW. The device operates within a temperature range of -40°C to +85°C and features viewing angles of 70° x 35°.

Feature Summary

• Oval dome lens design optimized for specific beam distribution
• High brightness output suitable for visible signage applications
• Through-hole mounting configuration for standard PCB integration

Applications

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

Procurement Notes

Verify the exact suffix CT0W0BB2 against official Cree LED documentation to confirm lens tint and binning specifications. Ensure compatibility with existing thermal management designs given the 130 mW power rating. Cross-reference the 621 nm peak wavelength requirement with system optical filters. Confirm that the T-1 3/4 form factor fits the mechanical constraints of the target enclosure.

Selection Notes

Select this component when high-intensity red illumination is required for outdoor or high-ambient-light environments. The oval shape provides distinct horizontal and vertical viewing angles, making it suitable for directional visibility needs. Consider the through-hole construction for robust mechanical attachment compared to surface-mount alternatives. Evaluate the 2.1 V forward voltage drop for driver circuit efficiency.

Part Context

This part belongs to the Screen Master 5-mm Oval LED series, designed specifically for demanding signage applications. The C566C family offers enhanced reliability and color consistency compared to standard LEDs. It serves as a specialized solution for message boards and information displays where precise color rendering and high luminous intensity are critical for daytime readability.
