GUS-QS8A-03-1783-GF Description

The GUS-QS8A-03-1783-GF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in modern electronics. This 16-pin QSOP (Quarter Small Outline Package) device features 8 isolated resistors, each with a 178K Ohm resistance value and a tight 2% tolerance. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it delivers reliable performance in compact designs. The thin-film technology ensures excellent stability, supported by a low ±25ppm/°C temperature coefficient, making it ideal for environments with fluctuating thermal conditions. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its 100V maximum voltage rating enhances durability in high-voltage circuits.
