GUS-QS8A-03-3090-DA Description

The GUS-QS8A-03-3090-DA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 8-resistor isolated network features a 309Ω resistance value with an ultra-tight 0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a compact 16-pin QSOP package with gull-wing SMD termination, it offers a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for high-density PCB designs. The non-automotive, non-PPAP compliant device is supplied in tube packaging and is ideal for precision analog and digital circuits.

GUS-QS8A-03-3090-DA Features
