GUS-QS8A-03-73R2-FF Description

The GUS-QS8A-03-73R2-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 terminations, this surface-mount device offers a 73.2Ω 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. Its 0.75W (3/4W) total power rating and 100V maximum voltage rating make it suitable for demanding circuits requiring reliable isolation (denoted by ISOL circuit designator). The QSOP package (4.9mm x 6.02mm x 1.47mm) features a 0.64mm terminal pitch for compact PCB layouts.
