YELLOW GMA 2885C GMC 2885C HER GMA 2985C GMC 2985C GREEN GMA 2485C GMC 2485C BICOLOR RED/GREEN GMA 2685C These are 5x8 dot matrix displays with large emitting area (0.2 diameter) LED sources. The GMX2X85C series are single color displays with the exception of GMA2685C which is a bicolor of red/green displays. All displays have gray face and white dot color. Other face or dot colors are available with minimum requirement. The X in GMX denotes row anode or row cathode. 2.3" (58.4 mm) character height Low power requirement High contrast & brightness Wide viewing angle 130 5 x 8 array with X-Y select Compatible with USASCII and EBCDIC codes X-Y stackable Choice of two matrix orientation anode or cathode column Easy mounting on PCB Categorized for luminous intensity Single color displays have the choice of 3 bright colors yellow/orange/green m Multicolor color displays are applicable to 3 bright colors greens, orange (HER) and yellow (green and HER mixed)a 2.3"5x8 OPTOELECTRONICS DOT MATRIX DISPLAYS PARAMETER YELLOW HER GREEN UNITS Power dissipation per dot/color ............... 60 70 75 mw Peak forward current per dot/color (duty cycle 1/10, 10KHz) .................. 80 100 100 mA Continuous |; per dot/color ...............0 00. 20 25 25 mA Reverse voltage V, per dot/color .............. 5 5 5 v Operating and storage temperature range . 6... kc en eee e teen ene cece tne b ee eer veneers 26C to +85C Soldering time at 260C (Ye inch below seating plane) ..... 0.66. e ete tee cece cent ieee e teen ete t eee es 3 sec INTERNAL PART NO.
