LA-501MD ROHM

Single Digit LED Numeric Display LA-501 D / N Series Datasheet The LA-501DN series were designed to meet the need for 13mm single-digit numeric displays. These LED numeric displays use GaAsP on GaP (Red) , GaP (Green) for the emitting material and are housed in an epoxy resin package. They are single-digit displays with a character height of 13.0mm. Features 1) Height of character: 13.0mm 2) Common anode and common cathode configurations are available for each color. 3) High-efficiency reflectors are used to achieve a bright, clear display. 4) The package surface is painted black and the segments are colored the display color.
