KF2004-GF50A

KF2004-GF50A Printheads Compact low voltage thick film thermal printhead (8dots / mm) KF2004-GF50A A world first, ROHM offers the KF2004-GF50A of thermal printheads that allow operation using a single standard lithium ion battery: required voltage has been reduced to just 2.7V. Compact and lightweight they are ideal printheads for handheld printers and PDAs (personal digital assistants). !Applications Mobile printers FET-POS printers Hand-held printers Debit printers !Features 1) Using advanced LSI technology, ROHM has developed a dedicated low voltage driver chip. Compared with previous products, power consumption has been reduced by more than 30%. Because the print head circuits draw just 2.7 volts, the printer can be driven using a single lithium ion battery. 2) One rank resistance value of 123Ω ± 4% eliminates the inconvenience of rank selection. 3) The GP10 series has a resistance value of 123Ω and can be used in devices designed to operate with a single 3V lithium ion battery. !External dimensions (Units : mm) 117 Max.1.7 Dot #1 MAX.16.5 2.1±0.3 104 (Effective Print Width) Dot #832 (11.35) (1.1) Exposed Conductor Side (14) ax .φ 14 . 0 No.28 No.1 Connector M Insert Direction 1/4 KF2004-GF50A Printheads !Equivalent circuit VH L-GND P-GND 1,2,3,26,27,28 18 13,14,15,16,17 13 24 23 12 11 3 2 1 DOT #832 DOT #1 STB7 STB6 STB2 STB1 AEO2 AEO1 LAT 9 8 20 19 5 LATCH REGISTER DI CLK DO VDD TM TM 25 6 4 7 11 12 THERMISTOR 30kΩ B:3950 SHIFT REGISTER Fig....
