GUS-QS8A-03-56R0-GD Description

The GUS-QS8A-03-56R0-GD 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 56Ω resistance per resistor with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient. Its isolated (ISOL) circuit design ensures independent resistor functionality, making it ideal for complex circuit isolation requirements. 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 dimensions (4.9mm x 6.02mm x 1.47mm) and ±0.1mm height tolerance ensure compatibility with high-density PCB designs.
