SE2004-DC90A printhead is a high-speed, high-quality, and high-durability thermal printhead that achieves high corrosion resistance, better resistance against scratching damage, and high efficiency through high-performance partial glaze and highly conductive overcoat layer. SE200*-DC90A series are lined up which can accommodate with all types of barcode labeling printers from Direct to Thermal Transfer, normal to high speed (over 300mm/s).
The SE2004-DC90A is a high‑speed thermal printhead featuring an 8‑dot/mm resolution and ROHM’s STEP FREE structure, which provides high corrosion resistance, scratch resistance, and high efficiency. It is compatible with a wide range of barcode label printers, including direct thermal and thermal transfer models, and supports printing speeds over 300 mm/s.
The document includes external dimensions, electrical characteristics, timing charts, equivalent circuit diagrams, and performance curves. It also contains legal notices and export‑control information, advising users to consult ROHM sales representatives before employing the product in safety‑critical equipment such as medical or aerospace devices.
