GUS-QS8A-02-1270-FD Description

The GUS-QS8A-02-1270-FD from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a 16-pin QSOP package with gull-wing SMD termination, this device offers a 127Ω resistance per resistor with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient. Its 0.75W (3/4W) total power rating and 0.1W per resistor ensure reliable operation in demanding environments, supported by a 100V maximum voltage rating and an extended -70°C to +125°C operating range. The isolated (ISOL) circuit design enhances signal integrity, making it ideal for noise-sensitive applications.
