GUS-QS8A-02-3400-DB Description

The GUS-QS8A-02-3400-DB is a high-precision thin-film resistor network manufactured by TT Electronics/IRC, designed for demanding surface-mount (SMD) applications. This 8-resistor isolated network features a 340Ω resistance value with a tight 0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a 16-pin QSOP package with gull-wing terminations, it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) and a 0.64mm terminal pitch, making it ideal for high-density PCB designs. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this component is engineered for reliability in precision analog and digital circuits.
