GUS-QS8A-02-28R0-FF Description

The GUS-QS8A-02-28R0-FF 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 28Ω resistance per resistor with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient. Its isolated (ISOL) circuit design ensures independent resistor functionality, making it ideal for complex circuit topologies. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it operates reliably across a wide temperature range of -70°C to +125°C. The compact 4.9mm × 6.02mm × 1.47mm footprint and 0.64mm terminal pitch enable high-density PCB layouts.
