GUS-QS8A-03-1743-GF Description

The GUS-QS8A-03-1743-GF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP surface-mount device features eight isolated resistors, each with a 174KΩ resistance value and a tight 2% tolerance. With a ±25ppm/°C temperature coefficient, it ensures stable performance across a wide operating temperature range of -55°C to +125°C. The network supports a derated power range of 70°C to 125°C, with a total power rating of 0.75W (3/4W) and 0.1W (1/10W) per resistor. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting in space-constrained designs.
