GUS-QS8A-03-9310-FA Description

The GUS-QS8A-03-9310-FA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 931Ω resistance value per resistor with a tight 1% tolerance and a low ±25ppm/°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 length × 6.02mm depth × 1.47mm height) and a 0.64mm terminal pitch, making it ideal for space-constrained PCB designs. With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, it balances power handling and precision in demanding environments.

GUS-QS8A-03-9310-FA Features

• Thin-Film Technology: Delivers superior accuracy, low noise, and excellent long-term stability.
• High Power Handling: 0.1W per resistor (0.75W total) with derating up to 125°C, outperforming standard thick-film networks.
• Isolated Design (ISOL): Each resistor operates independently, reducing crosstalk in sensitive circuits.
• Robust Construction: QSOP package with gull-wing leads ensures reliable surface-mount assembly and mechanical durability.
• Wide Operating Range: Suitable for industrial and instrumentation applications with -55°C to +125°C capability (derated power).
• Non-Automotive/Non-PPAP: Optimized for commercial and industrial use where PPAP compliance is not required.

GUS-QS8A-03-9310-FA Applications

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor conditioning in test equipment.
• Medical Electronics: Patient monitoring systems requiring stable, low-drift resistance.
• Communication Systems: Impedance matching and signal termination in RF modules.
• Industrial Controls: PLCs and motor drives where isolation and thermal stability are critical.
• Power Management: Current sensing and load balancing in DC-DC converters.

Conclusion of GUS-QS8A-03-9310-FA

The GUS-QS8A-03-9310-FA stands out for its thin-film precision, isolated design, and compact QSOP package, making it a superior choice over thicker-film or non-isolated alternatives.
