GUS-QS8A-02-9531-CA Description

The GUS-QS8A-02-9531-CA from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. With a 9.53KΩ resistance per resistor, a tight 0.25% tolerance, and a low ±50ppm/°C temperature coefficient, this component ensures stable performance in precision analog and digital circuits. Packaged in a 16-pin QSOP with gull-wing terminations, it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) and a 0.64mm terminal pitch for high-density PCB layouts. Rated for 0.75W total power dissipation (0.1W per resistor) and 100V maximum voltage, it operates reliably across a -70°C to +125°C temperature range. The isolated (ISOL) circuit design enhances flexibility in circuit configurations.
