End of Life May-2021 TLHB44K2M1 www.vishay.com Vishay Semiconductors High Efficiency Blue LED, 3 mm Tinted Diffused Package FEATURES GaN on SiC technology Standard 3 mm (T-1) packagefie Small mechanical tolerances Wide viewing angle Very high intensity Luminous intensity categorized 19222 ESD class 1 DESCRIPTION Material categorization: for definitions of compliance please see This device has been redesigned in 1998 replacing SiC by www.vishay.com/doc 99912 GaN technology to meet the increasing demand for high efficiency blue LEDs. APPLICATIONS It is housed in a 3 mm tinted diffused plastic package. Status lights All packing units are categorized in luminous intensity Off / on indicator groups. That allows users to assemble LEDs with uniform appearance.
