42-21UYC/S530-A3/TR8

LED Indication - Discrete Overview

The 42-21UYC/S530-A3/TR8 is a single-color yellow LED from Everlight Electronics, designed for surface mount technology (SMD) applications. It utilizes a 1206 (3216 metric) package with a rectangular lens shape and water-clear transparency to optimize light emission. The component operates at a peak wavelength of 589 nm and delivers a typical luminous intensity of 39 mcd under a forward current of 20 mA. Key electrical parameters include a forward voltage of 2 V and a power rating of 60 mW. The device is supplied in a reel packaging format, suitable for automated assembly processes.
