LB-303MK ROHM

Three-digit LED numeric displays Data sheet SLB-IM-30031A3SK SeTW1ries The LB-303AK series were designed to meet the need for multi-digit numeric displays. These LED numeric displays use GaAsP on GaP (red) , GaP (green) 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. lFeatures 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 and green. 4) The package surface is painted black and the segments are colored the display color. lDimensions (Unit : mm) lPin assignments Pin No. Function 1 Segment Digit 1 Common 2 3 Segment Digit 2 Common 4 Digit 3 Common 5 6 Segment D.P 7 Segment 8 Segment 9 Segment 10 Segment 11 Segment lInternal circuit schematic lSelection guide Emitting color Red Green Common Anode LB-303VA LB-303MA Cathode LB-303VK LB-303MK www.rohm.com 2015 ROHM Co., Ltd.
