GUS-QS8A-02-7870-BA Description

The GUS-QS8A-02-7870-BA from TT Electronics/IRC is a high-precision 8-resistor thin-film network designed for demanding surface-mount applications. Encased in a 16-pin QSOP package with gull-wing terminations, it offers a 787Ω resistance per element with an ultra-tight 0.1% tolerance and a low ±50ppm/°C temperature coefficient. Rated for 0.75W (3/4W) total power and 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 delivers superior stability and accuracy.
