Technical data sheet for the Everlight DLE-033-C51 white T-1 3/4 LED, detailing electro-optical characteristics and absolute maximum ratings.
This document is a technical datasheet for the Everlight DLE-033-C51 LED. It describes a popular T-1 3/4 colorless package designed for applications requiring high luminous intensity, such as message panels, optical indicators, backlighting, and marker lights. The device uses an InGaN chip with phosphor to produce ideal white light.
The datasheet provides comprehensive specifications including absolute maximum ratings like continuous forward current of 30 mA and reverse voltage of 5 V. It also details electro-optical characteristics such as luminous intensity ranging from 11,250 to 22,500 mcd at 20 mA, viewing angle up to 20 degrees, and chromaticity coordinates (x=0.33, y=0.33). Packaging information indicates availability in bulk or taped on reel.
