GUS-QS8A-03-5230-FB Description

The GUS-QS8A-03-5230-FB from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications in surface-mount PCB assemblies. Housed in a compact 16-pin QSOP (Quarter Small Outline Package) with gull wing termination, this isolated resistor network offers a 523Ω resistance per element with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient. Rated for 0.75W (3/4W) total power dissipation and 0.1W per resistor, it operates reliably across a wide temperature range of -70°C to +125°C, making it suitable for demanding environments. The 100V maximum voltage rating and thin film technology ensure stable performance with minimal noise, ideal for analog and mixed-signal circuits. Packaged in a tube for automated assembly, its 4.9mm x 6.02mm footprint and 1.47mm profile save board space without compromising durability.

GUS-QS8A-03-5230-FB Features
