GUS-QS8A-03-1132-DA Description

The GUS-QS8A-03-1132-DA 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 11.3KΩ resistance value with an ultra-tight ±0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -55°C to +125°C. Packaged in a 16-pin QSOP with gull-wing terminations, it offers a compact footprint (4.9mm x 6.02mm x 1.47mm) and a 0.64mm terminal pitch, making it ideal for high-density PCB designs. With a maximum voltage rating of 100V and a total power rating of 0.75W (0.1W per resistor), this component is engineered for reliability in precision analog and digital circuits.
