Low Noise and No Ink Required, Enhancing User Convenience

Rohm has developed a new structure thermal print head KR2002-D06N10A series that operates with a single cell Li-ion battery power supply.

A thermal print head is an electronic device that repeatedly generates and dissipates heat to print characters onto media such as thermal paper. Thermal print heads for payment terminals have conventionally been driven by a two-cell Li-ion battery power supply. This product improves heat retention by optimizing the glaze design of the heat retention layer and adopting a special low-resistance heating element.

Additionally, a new structure combining a ceramic substrate and a print circuit board has been developed, improving applied energy efficiency by approximately 20% compared to the company's two-cell power driven product and miniaturizing the head section. Through this new structure and material improvements, single-cell power supply operation enables the same speed as conventional products.
