KF2003-GF41A
Using its expertise in LSI technology, ROHM has developed new high density driver chips for use in the KF2003-GF41A .
Capable of being employed for both thermal and thermal transfer printing, with a print speed of 200mm/s, the resulting
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.

Features
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, the fastest in its class.
2) One rank resistance value of 650
3% eliminates the inconvenience of rank selection.
3) 2-inch, 3-inch and 4-inch series are available.
