SE3002-DC90A is a high speed thermal printhead that uses a high performance partial glaze and highly conductive overcoat layer to achieve high speed, high quality and high durability. SE300*-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 SE3002-DC90A is a high‑speed thermal printhead with a step‑free structure, high‑performance partial glaze, and a conductive overcoat layer. It is suitable for barcode, label, packaging, ATM, and ticket printers, supporting both direct and thermal‑transfer technologies.
The document lists detailed electrical characteristics, pin assignments, and external dimensions, and notes that external heat‑history control is required for high‑speed printing. Legal and export‑control notices are included in the appendix.
