Light Emitting Diodes displays The LB-402 DN series were designed to meet the need for multi-digit numer- ic dispiays. These LED numeric dis- plays use GaAsP on GaP for the emit- ting material (with the exception of green) and are housed an epoxy resin package. They are two-digit displays with a character height of 10.16 mm. @Features 1) Height of character : 10.16 mm. 2) Common anode and common cathode configurations are avail- able for each color. 3) The package surface is coated black and the segments are col- ored the display color. 4) High efficiency reflectors are used to achieve a bright, clear display. @Pin layout 1817 16 15 14 13 12 11 10 FF PP RE EH FT at az | 7, Th ae a1 | bt re] | - | oat KOK OX . | et; | I fet e2; | | lea | (patty [pe | Cow S i ana oO Digit T 5 py Digit 2D po ft tt ttt tt!
