GUS-QS0B-03-3571-BA Description

The GUS-QS0B-03-3571-BA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP surface-mount device integrates 19 resistors with a 3.57KΩ resistance value, offering 0.1% tolerance and an ultra-stable ±25ppm/°C temperature coefficient. With a 1W total power rating (0.05W per resistor), it operates reliably across a wide temperature range of 70°C to 125°C, making it suitable for precision analog and digital circuits. The gull-wing termination ensures secure PCB mounting, while the compact 8.66mm × 6.02mm × 1.47mm footprint optimizes board space. Packaged in a tube, this non-automotive, non-PPAP compliant component is ideal for industrial and instrumentation use.
