GUS-QS0B-03-9091-DC Description

The GUS-QS0B-03-9091-DC 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 with a 9.09KΩ resistance value, offering a tight 0.5% tolerance and a low ±25ppm/°C temperature coefficient for exceptional stability. Rated for 1W total power dissipation (0.05W per resistor), it operates reliably across a 70°C to 125°C derated range, with a maximum operating temperature of 125°C. Its 100V maximum voltage rating and gull-wing termination ensure robust performance in compact PCB layouts. Packaged in a tube, this non-automotive, non-PPAP-compliant component is ideal for precision analog and digital circuits.
