GUS-QS8A-02-3571-BA Description

The GUS-QS8A-02-3571-BA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerances and stable performance. This 16-pin QSOP (Quarter-Small Outline Package) device integrates 8 isolated resistors, each with a 3.57KΩ resistance and an exceptional ±0.1% tolerance. It operates within a wide temperature range of 70°C to 125°C (derated) and can withstand 125°C maximum operating temperature, making it suitable for harsh environments. With a ±50ppm/°C temperature coefficient, it ensures minimal resistance drift under thermal stress. The 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating further enhance its reliability in precision circuits.
