GUS-QS8B-03-4642-JG Description

The GUS-QS8B-03-4642-JG 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 15 resistors, each with a 46.4KΩ resistance value and a tight ±5% tolerance, ensuring consistent performance in demanding circuits. With a 0.75W (3/4W) total power rating and 0.05W (1/20W) per resistor, it balances power dissipation and compactness. The device operates across a wide temperature range of 70°C to 125°C, supported by a low ±25ppm/°C temperature coefficient, making it ideal for stable, high-accuracy designs.
