GUS-QS8A-02-7150-BB Description

The GUS-QS8A-02-7150-BB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerances and stable performance. This 8-resistor isolated network features a 715Ω resistance value per resistor with an exceptional 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. Encased in a 16-pin QSOP package with gull-wing SMD termination, it offers a compact footprint (4.9mm length × 6.02mm depth × 1.47mm height) and is supplied in tube packaging for automated assembly. Rated for 0.75W (3/4W) total power (0.1W per resistor), it operates reliably up to 125°C, with derated performance from 70°C to 125°C. Its 100V maximum voltage rating and isolated circuit designator (ISOL) make it suitable for precision analog and mixed-signal circuits.
