GUS-QS8A-02-7872-BA Description

The GUS-QS8A-02-7872-BA 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 78.7KΩ resistance value per resistor with an exceptional 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. Housed in a 16-pin QSOP package with gull-wing terminations, it offers a compact 4.9mm × 6.02mm footprint and a low profile (1.47mm height), making it ideal for space-constrained surface-mount (SMD) designs. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it operates reliably across a -70°C to +125°C temperature range, suiting both industrial and precision analog circuits.
