GUS-QS8A-03-5900-JB Description

The GUS-QS8A-03-5900-JB from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP package features 590Ω resistors with a 5% tolerance and a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating and 0.1W per resistor, it offers robust power handling in a compact 4.9mm × 6.02mm × 1.47mm footprint. The isolated (ISOL) circuit design and 100V maximum voltage rating make it suitable for applications requiring electrical separation and reliability. Packaged in a tube, this RoHS non-compliant component is ideal for industrial and commercial electronics where thin-film precision is critical.
