KA2003-BE10A Printheads Compact Battery drivable thick film thermal printhead (8dots / mm) KA2003-BE10A Compact and lightweight they are ideal print heads for handheld printers and PDAs (personal digital assistants). zApplications Mobile printers EFT-POS printers Hand-held printers Debit printers zFeatures 1) The B series brings reduced height of protective resin for IC and enlarged paper pathway for thermal papers. Thanks to ROHM’s latest LSI high integrated mounting technology and it’s ultra slim 192bit driver IC. 2) The B series accede the great world class low energy consumption characteristics of GP series. 3) Because the print heads circuits draw 2.7V, the printer can be driven using a single lithium battery. 80 Dot #576 (1.1) Dot #1 (7.35) Max.1.7 72 (Effective Print Width) Exposed Conductor Side ax No.1 M No.21 .φ 8. 0 (10) 1.4±0.3 MAX.12.5 zExternal dimensions (Unit : mm) Insert Direction Connector 1/4 KA2003-BE10A Printheads zEquivalent circuit DOT #576 VH DOT #1 L- GND VDD 5 4 3 2 1 STB5 STB4 STB3 STB2 STB1 LAT LATCH REGISTER DI SHIFT REGISTER C LK DO T H E R M I S TO R 30kΩ B:3950 TM TM Fig.1 zPin assignments No. Circuit No. Circuit 1 VH 12 VDD 2 VH 13 STB4 3 DO 14 STB5 4 LAT 15 N.C. 5 GND 16 GND 6 GND 17 GND 7 STB1 18 CLK 8 STB2 19 DI 9 STB3 20 VH 10 TM 21 VH 11 TM Note) The GND terminal 5 and 6 are not connected with the GND terminal 16 and 17.
