KF2002-GF94A
KF2002-GF94A is Compact low voltage thick film thermal printhead manufactured by ROHM.
Features
1) Both the circuit voltage and the voltage required during printing are 3.3V ; this allows the design of plete printer assemblies with energy-saving low power consumption. 2) KF2002-GF94A has a resistance value of 176Ω and can take a maximum current of 8.5V for printing. This is useful in applications where the peak voltage is restricted. 3) Because the connectors accept 1.25-mm pitch FFC (full flat cables) it is possible to reduce the size of printer mechanism control boards.
