GUS-QS8A-02-1783-JA Description

The GUS-QS8A-02-1783-JA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP package features 8 isolated resistors, each with a 178K Ohm resistance and a tight ±5% tolerance, ensuring reliable signal conditioning and voltage division. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it operates efficiently across a wide temperature range of 70°C to 125°C, derated for optimal thermal performance. The ±50ppm/°C temperature coefficient guarantees stability in fluctuating environments, while the 100V maximum voltage rating suits medium-voltage circuits. Its gull-wing termination and 0.64mm terminal pitch enable secure, high-density mounting.
