GUS-QS8A-03-9311-JB Description

The GUS-QS8A-03-9311-JB 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 9.31KΩ resistance value and a 5% tolerance, ensuring stable performance in demanding circuits. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it offers robust power handling while maintaining a compact footprint (4.9mm length × 6.02mm depth × 1.47mm height). The ±25ppm/°C temperature coefficient and 125°C maximum operating temperature make it suitable for environments with thermal fluctuations. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting.
