GUS-QS8A-02-8450-DA Description

The GUS-QS8A-02-8450-DA from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. Housed in a compact 16-pin QSOP package with gull wing terminations, it offers an 845Ω resistance value per resistor with an ultra-tight ±0.5% tolerance and a low ±50ppm/°C temperature coefficient. The isolated (ISOL) circuit design ensures independent resistor functionality, while the thin film technology delivers superior stability and accuracy. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it operates reliably across a 70°C to 125°C derated power range, peaking at 125°C maximum operating temperature. Its 4.9mm x 6.02mm footprint and 1.47mm profile make it ideal for space-constrained PCB designs.
