GUS-QS8B-00-4642-J Description

The GUS-QS8B-00-4642-J 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 environments. 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, derated for optimal reliability, and features a ±250ppm/°C temperature coefficient, making it stable under thermal stress. Its gull-wing termination and 0.64mm terminal pitch facilitate robust soldering in automated SMT processes.

GUS-QS8B-00-4642-J Features

• High-Density Integration: 15 resistors in a compact QSOP (4.9mm x 6.02mm x 1.47mm) package, ideal for space-constrained designs.
• Precision Thin-Film Technology: Delivers low noise and excellent stability compared to thick-film alternatives.
• Robust Power Handling: 100V maximum voltage rating and 125°C maximum operating temperature suit industrial and telecom applications.
