5977721102F

Overview

The Dialight 5977721102F is a surface-mount bi-color LED indicator featuring green and yellow elements in a 4-SMD, no-lead package. It emits at peak wavelengths of 565 nm (green) and 585 nm (yellow), with dominant wavelengths of 570 nm and 590 nm respectively. The device operates with a typical forward voltage of 2.1 V for green and 1.8 V for yellow, tested at 20 mA. Luminous intensity is rated at 16 mcd for both colors. It has a 120-degree viewing angle, non-diffused clear lens, and dimensions of 3.10 mm length by 2.80 mm width.
