GUS-QS8A-03-1912-BB Description

The GUS-QS8A-03-1912-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 19.1KΩ resistance value 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 operating range of -55°C to +125°C, derated up to 125°C. The 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for high-reliability applications. Its gull-wing termination and 0.64mm terminal pitch enable robust PCB mounting in space-constrained designs.
