GUS-QS8B-01-3090-J Description

The GUS-QS8B-01-3090-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 309Ω resistance value and a tight ±5% tolerance, ensuring reliable signal conditioning and voltage division. Rated for 0.75W (3/4W) total power dissipation and 0.05W (1/20W) per resistor, it operates across a wide temperature range of -70°C to +125°C, with a ±100ppm/°C temperature coefficient for stable performance in varying environments. The gull-wing termination and 0.64mm terminal pitch facilitate robust soldering in automated SMD processes.

GUS-QS8B-01-3090-J Features

• High-Density Integration: 15 resistors in a compact 4.9mm × 6.02mm × 1.47mm QSOP package, ideal for space-constrained designs.
• Thin-Film Technology: Delivers superior accuracy, low noise, and long-term stability compared to thick-film alternatives.
• Derated Power Handling: Supports 70°C to 125°C operation at reduced power, enhancing reliability in high-temperature environments.
