Compact medium speed thick film thermal printhead (8dots / mm)
KD2003-CF10A
The KD2003-CF10A is ideal for applications that require compact, lightweight thermal printheads, such as POS and label printer applications. The 203dpi has a resolution of the 2-, 3-, 4-, and 8-inch sizes. This series is suitable for a wide range of applications. zApplications POS printers Label printers Receipt printers General purpose compact printers zFeatures 1) Both ROHM’s advanced LSI technology and proprietary partial glaze are used to realize higher printing efficiency. With a high print speed of 100mm/s, this series is also suitable for thermal transfer printing. 2) Besides the fact that harness-type direct connectors at either end allow wring to be fitted as convenient, the thermal printheads can be applied directly to the substrate without a heat sink. Both these features give engineers greater freedom when designing the printer mechanism. 3) One rank resistance value of 800Ω ± 3% eliminates the inconvenience of rank selection. 4) The required driving voltage of 3.13 to 5.25V allows wide range of power supply voltage setting. This also allows multiple choice of electronic components for printers. zExternal dimensions (Unit : mm)
