GUS-QS8A-02-4020-GB Description

The GUS-QS8A-02-4020-GB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 402Ω resistance value per resistor with a tight 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Packaged in a 16-pin QSOP with gull-wing SMD termination, it offers a compact footprint (4.9mm x 6.02mm x 1.47mm) and is supplied in tube packaging for automated assembly. With a maximum voltage rating of 100V and a total power rating of 0.75W (0.1W per resistor), this component is engineered for reliability in demanding circuits.

GUS-QS8A-02-4020-GB Features

• Thin-film technology for superior accuracy and stability.
• Isolated circuit design (ISOL) for independent resistor performance.
• High power density: 0.75W total power in a compact QSOP package.
• Wide operating range: -55°C to +125°C (derated power up to 125°C).
• Gull-wing SMD termination for robust PCB mounting and solderability.
• Low TCR (±50ppm/°C) minimizes resistance drift under thermal stress.
• RoHS non-compliant (suitable for legacy or exempt applications).

GUS-QS8A-02-4020-GB Applications

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

• Voltage dividers and signal conditioning in industrial sensors.
• Feedback networks for op-amps and ADCs/DACs.
• Impedance matching in communication systems.
• Medical instrumentation requiring stable, low-drift resistance.
• Automotive subsystems (non-AECQ qualified, suitable for non-safety-critical uses).
