GUS-QS8A-03-1431-FB Description

The GUS-QS8A-03-1431-FB 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 1.43KΩ resistance value per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Packaged in a 16-pin QSOP with gull-wing terminations, it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) while delivering a total power rating of 0.75W (3/4W) and 0.1W per resistor. Its 100V maximum voltage rating and thin-film technology make it ideal for precision analog and digital circuits.
