GUS-QS8A-03-2321-JB Description

The GUS-QS8A-03-2321-JB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP package integrates 8 isolated resistors, each with a 2.32KΩ resistance value and a tight ±5% tolerance, ensuring consistent performance across demanding environments. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it delivers reliable power dissipation while maintaining stability. The device operates over a wide temperature range of -70°C to +125°C, with a low ±25ppm/°C temperature coefficient, minimizing resistance drift under thermal stress. Its gull-wing termination and 0.64mm terminal pitch facilitate easy soldering and high-density board layouts.
