Thick film thermal printhead
(11.8 dots / mm)
KD3008-DF10A
Using its expertise in LSI technology, ROHM has developed new high density driver chips for use in the KD3008-DF10A .
Capable of being employed for both thermal and thermal transfer printing, with a print speed of 200mm/s, the resulting
print heads 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.

zFeatures
1) The use of a special partial glaze and the latest heating element structure, along with new high-density driver chips 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 components for printers.
4) 2-inch, 3-inch, 4-inch and 8-inch series are available.
