LB-303AK

LB-303AK Series LED displays High efficiency, three-digit numeric displays LB-303AK Series The LB-303AK series were designed to meet the need for multi-digit numeric displays. These LED numeric displays use GaAsP on GaP for the emitting material (with the exception of green) and are housed in an epoxy resin package. They are three-digit displays with a character height of 8.0 mm. !External dimensions (Units : mm) 22.0 7.0 7.0 10° 8.0 13.0 1.0 4.0 3- φ 0.9 !Features 1) Height of character : 8.0 mm 2) High efficiency in a compact package. 3) Common anode and common cathode configurations are available for red, orange and green. 4) The package surface is painted black and the segments are colored the display color.
