C566D-BFF-CU14Q4S1

Overview

The C566D-BFF-CU14Q4S1 is a single-color blue LED from the Screen Master series by Cree LED. It features a 470 nm wavelength and emits blue light through a tinted, diffused oval dome lens measuring 5.20 mm x 4.60 mm. Designed for through-hole radial mounting, it operates with a typical forward voltage of 3.4 V at a test current of 20 mA. The component has a maximum power rating of 140 mW and provides an optical intensity of 2042 mcd. It offers a viewing angle of 70° x 30° and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Features a tinted blue oval dome lens with diffused transparency for optimized light distribution.
• Designed for through-hole radial installation in standard T-1 3/4 (5 mm) form factors.
• Delivers high luminous intensity suitable for discrete indicator applications.

Applications

• Discrete electronic indicators
