GUS-QS8A-03-4531-CA Description

The GUS-QS8A-03-4531-CA from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. With a 4.53KΩ resistance per resistor, a tight ±0.25% tolerance, and a low ±25ppm/°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 derated power range, with a 125°C maximum operating temperature. The isolated (ISOL) circuit design enhances signal integrity in multi-channel systems.
