GUS-QS8A-02-1431-DB Description

The GUS-QS8A-02-1431-DB from TT Electronics/IRC is a high-precision 8-resistor thin-film network designed for demanding surface-mount applications. Encased in a compact 16-pin QSOP package with gull-wing terminations, it offers a 1.43KΩ resistance per element with an ultra-tight ±0.5% tolerance and a low ±50ppm/°C temperature coefficient. Rated for 0.75W (3/4W) total power dissipation (0.1W per resistor), it operates reliably across a wide temperature range of 70°C to 125°C, with a maximum voltage rating of 100V. Its isolated (ISOL) circuit design ensures independent resistor performance, while the thin-film technology guarantees stability and low noise.
