GUS-QS8A-03-6980-DA Description

The GUS-QS8A-03-6980-DA from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding electronic applications. Housed in a compact 16-pin QSOP package with gull wing termination, it offers a 698Ω resistance value per resistor with an exceptional ±0.5% tolerance and a low ±25ppm/°C temperature coefficient. Rated for 0.75W (3/4W) total power dissipation and 0.1W per resistor, this device operates reliably across a wide temperature range of -55°C to +125°C, with derated performance up to 125°C. Its 100V maximum voltage rating and isolated circuit design (ISOL) make it suitable for precision analog and digital circuits.
