KF3002-GD31A is Compact high speed thick film thermal printhead manufactured by ROHM.
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 with using thermal history control, the fastest in its class. 2) One rank resistance value of 1250Ω ± 3% eliminates the inconvenience of rank selection. 3) 2-inch, 3-inch and 4-inch series are available.
