GUS-QS8A-02-2203-DA Description

The GUS-QS8A-02-2203-DA is a high-precision 220K Ohm thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount (SMD) applications. Housed in a compact 16-pin QSOP package with gull-wing termination, this 8-resistor isolated network offers exceptional stability with a ±50ppm/°C temperature coefficient and a tight 0.5% tolerance. Rated for 0.75W (3/4W) total power and 0.1W per resistor, it operates reliably across a wide temperature range (-70°C to +125°C), making it suitable for harsh environments. The 100V maximum voltage rating and thin-film technology ensure low noise and high accuracy, while the isolated circuit design (ISOL) provides flexibility in circuit configurations.
