5YDL-F

LED Indication - Discrete Overview

The 5YDL-F is a single-color yellow LED from Bivar Inc., designed for through-hole mounting in a T-1 3/4 (5 mm) package. It features a diffused lens with a 40-degree viewing angle and emits at a dominant wavelength of 590 nm. The component operates with a typical forward voltage of 2 V at a test current of 2 mA, producing an optical intensity of 4 mcd. This radial LED is currently classified as obsolete.
