GUS-QS8A-02-4122-DA Description

The GUS-QS8A-02-4122-DA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 8-resistor isolated network features a 41.2KΩ resistance value with an ultra-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 compact 16-pin QSOP package, 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-reliability circuits. The gull-wing termination ensures secure PCB mounting, while the isolated circuit design (ISOL) provides flexibility in circuit configurations.
