SE2003-DC90A printhead is a 1/5 high precision thermal printhead developed by ROHM Semiconductor. It features high speed, high quality, high durability and is suitable for label printers, ticket printers, and general-purpose compact printers.
The SE2003-DC90A is a high‑speed, high‑quality thermal printhead featuring ROHM’s STEP FREE structure, high corrosion resistance, and a conductive overcoat layer. It delivers a print resolution of 8 dots/mm and supports printing speeds over 300 mm/s, making it suitable for a wide range of barcode labeling printers, ticket printers, and compact printers.
The datasheet includes detailed mechanical dimensions, electrical parameters, timing charts, and equivalent circuit diagrams. It notes that the printhead does not contain internal heat‑history control, so external control is required for high‑speed operation. Compatibility with the SE3003-DC90A 300 dpi mechanical specifications is also documented.
