GUS-QS8A-01-6811-JA Description

The GUS-QS8A-01-6811-JA 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 features 8 isolated resistors, each with a 6.81KΩ resistance value and a 5% tolerance, ensuring reliable signal conditioning and voltage division. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it operates efficiently across a wide temperature range of 70°C to 125°C, derated for optimal thermal performance. The ±100ppm/°C temperature coefficient guarantees stability in varying environmental conditions, while the 100V maximum voltage rating supports robust circuit protection.

GUS-QS8A-01-6811-JA Features

• Thin-Film Technology: Delivers superior accuracy, low noise, and long-term stability compared to thick-film alternatives.
• Isolated Resistors (ISOL): Each of the 8 resistors operates independently, ideal for multi-channel isolation.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), saving board space in dense layouts.
• Gull Wing Termination: Ensures secure surface-mount attachment with a 0.64mm terminal pitch for automated assembly.
• High Power Handling: 0.75W total dissipation and 0.1W per resistor enable use in power-sensitive designs.
• Wide Operating Range: Functions reliably from -55°C to +125°C, with derated performance up to 125°C.

GUS-QS8A-01-6811-JA Applications

This resistor network excels in:

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor interfaces requiring tight tolerance (±5%).
• Industrial Control Systems: PLCs, motor drives, and instrumentation where thermal stability (±100ppm/°C) is critical.
• Telecommunications: Signal conditioning in RF modules and baseband processing.
• Medical Electronics: Isolated measurement circuits in patient monitoring equipment.
• Automotive (Non-Automotive Rated): Prototyping or non-safety-critical automotive subsystems.
