GUS-QS0B-02-4322-CB Description

The GUS-QS0B-02-4322-CB is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount (SMD) applications. This 20-pin QSOP package integrates 19 resistors with a 43.2K Ohm resistance value, offering a tight 0.25% tolerance and a low ±50ppm/°C temperature coefficient. With a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, it operates reliably across a wide temperature range of -70°C to +125°C. The gull-wing termination ensures secure PCB mounting, while the compact 8.66mm × 6.02mm × 1.47mm footprint suits space-constrained designs. Packaged in a tube, it is ideal for automated assembly processes.
