The RT1206BRD071K78L is a surface mount thin-film resistor manufactured by the Yageo Corporation. It has a resistance of 1.78 kohm, a tolerance of 0.1%, and a temperature coefficient of 25ppm/K. The component is constructed using a nickel barrier layer with a thin-film resistive element comprised of ceramic with a gold metallization layer. The surface mount design allows for very precise placement on the printed circuit board, providing higher accuracy with better reliability and durability than leaded components. Additionally, the thin-film construction of the component helps to reduce noise and enhances frequency characteristics, making it suitable for use in RF and high-frequency circuits.
