Compact low
voltage thick film thermal printhead (8dots / mm)
KF2002-GF71A
These compact, lightweight printheads have low power requirements and are intended for ECR and mobile applications. Drawing 7.2V, a maximum print speed of 2 inches per second is possible.
!Applications ECR printers Hand-held printers
!Features 1) A wide range of power supply
voltage, from 4.2V-8.5V, can be used to drive the printhead. This gives the flexibility for use with printers designed to operate with power from various battery configurations. 2) To allow the design of compact printers for use in calculators and other mobile applications, the basic specifications of the unit have been standardized. This gives engineers greater freedom to develop mechanical designs. 3) One rank resistance value of 210Ω ± 4% eliminates the inconvenience of rank selection.
