GUS-QS8A-03-5361-FB Description

The GUS-QS8A-03-5361-FB 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, it offers a 5.36KΩ resistance per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide -70°C to +125°C operating range. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, this isolated (ISOL) network is ideal for demanding analog and digital circuits. The 4.9mm x 6.02mm x 1.47mm compact footprint and ±0.1mm dimensional tolerances make it suitable for high-density PCB designs.
