1. ROHM Data Sheet SEMICONDUCTOR Compact medium speed thick film thermal printhead 8dots mm KD2008 CG50A KD2008 CG50A is suitable for devices such as high speed POS and label printer applications that require thermal printheads capable of higher printing rates Improved power circuit design means that with heavier current it is possible to print at speeds as high as 125 mm s The GK Series is the thus ideal for label printers that need high printing rates Applications POS terminal printers Label printers CAT printers General purpose compact printers Features 1 Using a special compact partial glaze and new heating element structure achieves high speed printing at 125 mm s 2 The use of the newly developed highly durable conductive protective film has improved countermeasures against static electricity 3 The VH and GND sections of the power circuitry have been strengthened so that heavier current can be applied 4 Ultra small connectors designed to conform with FFCs and miniature driver chips have been used Although the resulting printheads are surprisingly compact and lightweight they can be used with large platens of up to 20 mm in diameter 5 One rank resistance value of 800Q 3 eliminates the inconvenience of rank selection Dimensions Units mm 230 5 0 3 Heatsink Width 216 0 2 Effective Print Width annann nmang No 28 Wei _No 28 Con2. age resistance value Rave 800 Q Applied voltage Vi 24 V Applied power Po 0 5 W dot Print cycle SLT 1 ms Pulse width Ton 0 4 ms Maximum number of dots energized simultaneously 432 dots Maximum clock frequency 5 MHz Maximum roller diameter 20 mm Running life pulse life 50 5x107 km pulses Operating temperature 5 45 C CON com 3 4 2010 02 Rev A 2010 ROHM Co Ltd All rights reserved KD2008 CG50A Data Sheet Electrical characteristic curves 0 8 0 45 F50 HDA OJI SLT 1 00ms line 0 7 0 4 0 6 0 35 e gt E 8 05 D 8 03 5 Z E Ww 0 25 gt 0 4 a gt E 02 u 0 3 D Gi a fi 0 15 O Se 0 1 0 1 0 05 Do 1 2 3 4 5 0 00 0 05 0 10 0 15 0 20 025 0 30 05 05 1 15 2 25 27 SCANNING LINE TIME ms line ENERGY mJ dot SCANNING LINE TIME ms line Fig 3 Adaptive speed chart Fig 4 Representative density curve Fig 5 Maximum energy curve 180 160 140 l 120 6 100 80 a fi 60 a 40 20 0 gege 20 10 0 10 20 30 40 50 60 70 TEMPERATURE C Fig 6 Thermistor curve CON com 414 2010 02 Rev A 2010 ROHM Co Ltd All rights reserved Notice Notes No copying or reproduction of this document in part or in whole is permitted without the conse
