GUS-QS8A-02-1781-JF Description

The GUS-QS8A-02-1781-JF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP surface-mount device features 8 isolated resistors, each with a 1.78KΩ resistance and a 5% tolerance, ensuring reliable signal conditioning and voltage division. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it delivers robust performance in compact designs. The ±50ppm/°C temperature coefficient and 125°C maximum operating temperature make it suitable for stable operation across a wide thermal range (70°C to 125°C derated). Its gull-wing termination and 0.64mm pitch enable easy PCB integration, while the 1.47mm low-profile height saves space in dense layouts.
