GUS-QS0B-03-6981-CA Description

The GUS-QS0B-03-6981-CA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP device integrates 19 resistors with a 6.98KΩ resistance value, offering a tight ±0.25% 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 compatibility with automated PCB assembly processes. Packaged in a tube, this non-automotive, non-PPAP compliant component is ideal for precision analog and digital circuits.
