GUS-QS8A-03-7871-JB Description

The GUS-QS8A-03-7871-JB from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. Encased in a compact 16-pin QSOP package with gull wing termination, this surface-mount device offers a 7.87KΩ resistance per resistor with a 5% tolerance and a low ±25ppm/°C temperature coefficient. Its isolated (ISOL) circuit design ensures independent resistor functionality, making it ideal for signal conditioning and voltage division. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it operates reliably across a 70°C to 125°C derated range, peaking at 125°C. The 100V maximum voltage rating and thin film technology ensure stability in demanding environments.
