KD2003-DG10A

Using its expertise in LSI technology, ROHM has developed new high density driver chips for use in the KD2003-DG10A .
Capable of being employed for bot h thermal and therm al transfer pr inting, with a print speed of 25 0mm/s, the resulti ng
printheads are the fastest in their class. The high-speed and high-density printing answers the needs of ATM, kiosk and
ticket printing devices, which are increasingly being called upon to produce graphical output.

zApplications

Label printers
Ticket printers
POS printers
ATM printers
KIOSK printers
T erminal printers

zFeatures

1) The use of a special partial glaze and the latest heating elemen t structure, along w ith new high-de nsity driver chip s that
can accept big current, has allowed ROHM to achieve print speeds of 250mm/s, the fastest in its class.

2) One rank resistance value of 650Ω ± 3% eliminates the inconvenience of rank selection.

3) The required driving voltage of 3.15 to 5.25V allows wide range of power supply voltage setting. This also allows
multiple choice of electronic co mponents fo r printers.

4) 2-inch, 3-inch and 4-inch series are available.
