GUS-QS0B-03-1071-GA Description

The GUS-QS0B-03-1071-GA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP (Quarter-Small Outline Package) device integrates 19 resistors with a 1.07KΩ resistance value, offering a tight 2% tolerance and a low ±25ppm/°C temperature coefficient. Rated for 1W total power dissipation (0.05W per resistor), it operates reliably across a wide temperature range of 70°C to 125°C, with a maximum operating temperature of 125°C. Its gull-wing termination and 0.64mm terminal pitch ensure secure PCB mounting, while the compact 8.66mm x 6.02mm x 1.47mm footprint suits space-constrained designs. Packaged in a tube, this non-automotive and non-PPAP compliant component is ideal for precision analog and digital circuits.
