5977721202F

LED Indication - Discrete Overview

The Dialight 5977721202F is a discontinued surface-mount bi-color LED indicator from the microLED series. It features a 4-PLCC package with dimensions of 3.10mm length, 2.80mm width, and a maximum height of 2.05mm. The component emits green light at a peak wavelength of 565nm and yellow light at 585nm. Typical forward voltages are 2.1V for the green element and 1.8V for the yellow element. Luminous intensity is rated at 16mcd for both colors. It operates within an industrial temperature range and utilizes a clear, round lens with a flat top.
