GUS-QS8A-02-3571-DB Description

The GUS-QS8A-02-3571-DB 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 3.57KΩ resistance value per resistor 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 with gull-wing terminations, it offers excellent power handling with 0.1W per resistor and a total power rating of 0.75W (3/4W). Its 100V maximum voltage rating and thin-film technology make it ideal for precision analog and digital circuits.
