GUS-QS0B-03-9312-B Description

The GUS-QS0B-03-9312-B from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP package integrates 19 resistors, each with a 93.1kΩ resistance value and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy in circuit designs. With a ±25ppm/°C temperature coefficient, it delivers stable performance across a wide temperature range (70°C to 125°C derated, 125°C max). The network supports a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for precision analog and digital systems. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting.
