GUS-QS8A-02-3322-CA Description

The GUS-QS8A-02-3322-CA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package features 8 isolated resistors, each with a 33.2KΩ resistance, a tight 0.25% tolerance, and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating and 0.1W per resistor, it delivers robust power handling in a compact 4.9mm x 6.02mm x 1.47mm footprint. The gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB assembly, while the 100V maximum voltage rating enhances versatility in high-voltage circuits.
