KD3002-DF10A
Using its expertise in LSI technolo gy , R OHM has developed new high density driver ch ips for use in the KD3002-DF10A .
Capable of being employed for bot h thermal and therm al transfer pr inting, with a print speed of 20 0mm/s, the resulti ng
print heads are the fastest in their class. The high -spe ed and hi gh-d en sity prin ti ng answers the needs of ATM, kiosk and
ticket printing devices, which are increasingly being called upon to produce graphical output.

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 200mm/s with using thermal history control, the
fastest in its class.
2) One rank resistance value of 1000Ω ± 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, 4-inch and 8-inch series are available.
