Thick film thermal printhead
(8dots / mm)
KA2008-AF10A
The KA2008-AF10A is a standard type A4-size thick-film thermal printhead, developed mainly for facsimiles.
zApplications
Facsimiles
Electric whiteboard
Measuring terminal printers
zFeatures
1) Providing easy design solution of power supply with the same bit number for each strobe at A4 size FAX application by
employing the first in the industry 216 bits Driver IC.
2) Achieved Logic voltage of 3.13 to 5.25V and provides the wide range of power supply voltage. Wide selection of
electrical components is able to choose.
3) Employment of ROHM’s own technology clip connector makes it possible to supply the goods without heat sink and
substrate it self. This allows wide range of designing since substrate could be directly attached to the mechanism.
