GUS-QS0B-02-9102-DA Description

The GUS-QS0B-02-9102-DA 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 91 kΩ resistance value and a tight 0.5% tolerance, ensuring exceptional accuracy in circuit designs. With a ±50 ppm/°C temperature coefficient, it delivers stable performance across a wide operating range of -70°C to +125°C, making it suitable for environments with fluctuating thermal conditions. The network supports a maximum voltage rating of 100V and offers a total power rating of 1W (0.05W per resistor), providing reliable power dissipation in compact layouts. Its gull-wing termination and 0.64mm terminal pitch facilitate easy PCB assembly, while the 1.47mm low-profile height optimizes space efficiency in high-density designs.
