GUS-QS8A-03-1053-BB Description

The GUS-QS8A-03-1053-BB 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 105KΩ resistance per resistor with an ultra-tight 0.1% tolerance and a low ±25ppm/°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, making it ideal for precision analog and digital circuits.
