GUS-QS8A-02-9312-CA Description

The GUS-QS8A-02-9312-CA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 8-resistor isolated network features a 93.1KΩ resistance value with an ultra-tight 0.25% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a compact 16-pin QSOP package, it offers a 0.75W (3/4W) total power rating (0.1W per resistor) and supports a maximum voltage rating of 100V. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB assembly, while the 1.47mm low-profile height makes it suitable for space-constrained designs.

GUS-QS8A-02-9312-CA Features
