GUS-QS8A-03-1022-BB Description

The GUS-QS8A-03-1022-BB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP-packaged device features 8 isolated resistors, each with a 10.2KΩ resistance and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±25ppm/°C temperature coefficient, it delivers stable performance across a wide temperature range (70°C to 125°C derated, 125°C max). The 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for high-reliability environments. Its gull-wing termination and 0.64mm pitch enable compact PCB layouts in space-constrained designs.
