GUS-QS8A-02-9090-FA Description

The GUS-QS8A-02-9090-FA from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. Housed in a 16-pin QSOP package with gull wing termination, this surface-mount device offers a 909Ω resistance value per resistor with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient. Rated for 0.75W (3/4W) total power dissipation and 0.1W (1/10W) per resistor, it operates reliably across a wide temperature range of -55°C to +125°C, with derated performance up to 125°C. Its isolated (ISOL) circuit design ensures independent resistor functionality, making it ideal for signal conditioning and impedance matching.
