GUS-QS8A-03-1401-JB Description

The GUS-QS8A-03-1401-JB 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 component offers a 1.4KΩ 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 complex circuit layouts. 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 temperature range, peaking at 125°C maximum. The compact 4.9mm x 6.02mm x 1.47mm footprint and 0.64mm terminal pitch enable high-density PCB integration.
