GUS-QS8A-01-3571-GG Description

The GUS-QS8A-01-3571-GG 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 3.57KΩ resistance, 2% tolerance, and a ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is engineered for reliability in demanding environments. Its gull-wing termination and 0.64mm terminal pitch facilitate easy soldering and high-density mounting.

GUS-QS8A-01-3571-GG Features

• Thin-Film Technology: Delivers superior accuracy, low noise, and excellent thermal stability compared to thick-film alternatives.
• Isolated Resistors (ISOL): Each of the 8 resistors operates independently, ideal for applications requiring signal isolation.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), optimizing board space in densely populated designs.
• High Power Handling: 0.75W total dissipation (0.1W per resistor) supports robust performance in power-sensitive circuits.
• Wide Temperature Range: Operates reliably from -55°C to +125°C, with derated power up to 125°C.
• Gull-Wing SMD Termination: Ensures secure PCB attachment and compatibility with automated assembly processes.

GUS-QS8A-01-3571-GG Applications

This resistor network excels in precision analog and digital circuits, including:

• Signal Conditioning: Isolation and impedance matching in sensor interfaces (e.g., industrial RTDs, strain gauges).
• Voltage Division: Precision dividers in ADC/DAC reference circuits.
• Medical Electronics: Low-noise signal paths in patient monitoring equipment.
• Automotive & Industrial Systems: Despite lacking automotive PPAP compliance, its 125°C rating suits harsh environments like motor control or power management.
• Communications Equipment: Termination networks in high-frequency RF modules.
