GUS-QS0B-02-1431-DB Description

The GUS-QS0B-02-1431-DB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerances and stable performance. This 19-resistor array features a 1.43KΩ resistance value per resistor with an exceptional ±0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring reliable operation across a wide temperature range (70°C to 125°C). Housed in a 20-pin QSOP package with gull-wing SMD termination, it offers a compact footprint (8.66mm × 6.02mm × 1.47mm) and a 0.64mm terminal pitch, making it ideal for space-constrained PCB designs. Rated for 100V maximum voltage and 1W total power dissipation (0.05W per resistor), this network is suited for precision analog and digital circuits.
