GUS-QS8A-03-5900-DB Description

The GUS-QS8A-03-5900-DB from TT Electronics/IRC is a high-precision 8-resistor thin-film network designed for demanding surface-mount applications. Encased in a 16-pin QSOP package with gull-wing terminations, this isolated network offers a 590Ω resistance per resistor with an ultra-tight ±0.5% tolerance and a low ±25ppm/°C temperature coefficient. Rated for 0.75W (3/4W) total power and 0.1W per resistor, it operates reliably across a wide temperature range of 70°C to 125°C, with a maximum voltage rating of 100V. Its compact dimensions (4.9mm x 6.02mm x 1.47mm) and 0.64mm terminal pitch make it ideal for space-constrained PCB designs.
