GUS-QS8A-03-6040-GB Description

The GUS-QS8A-03-6040-GB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 604Ω resistance value per resistor with a tight 2% tolerance and an ultra-stable ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range of 70°C to 125°C. Packaged in a 16-pin QSOP (QSOP-16) case, it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) with gull-wing SMD termination, making it ideal for space-constrained PCB designs. The device supports a maximum voltage rating of 100V and delivers a total power rating of 0.75W (3/4W), with 0.1W (1/10W) per resistor, ensuring robust operation in demanding circuits.

GUS-QS8A-03-6040-GB Features

• Thin-Film Technology: Provides superior stability, low noise, and high precision compared to thick-film alternatives.
• Isolated Resistor Network (ISOL): Each resistor operates independently, reducing crosstalk and improving signal integrity.
• High Power Handling: 0.75W total power dissipation with derating up to 125°C, suitable for thermally challenging environments.
• Compact QSOP Package: 0.64mm terminal pitch and 1.63mm seated height enable high-density PCB layouts.
• Wide Operating Range: Functions reliably from -55°C to +125°C, making it versatile for industrial and commercial applications.
• Non-Automotive (PPAP No): Optimized for general electronics rather than automotive-grade requirements.
