GUS-QS8A-02-4642-FA Description

The GUS-QS8A-02-4642-FA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 8 isolated 46.4KΩ resistors with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it delivers reliable power handling in compact designs. The gull-wing termination and 0.64mm pitch facilitate easy PCB assembly, while the 1.47mm low-profile height suits space-constrained applications.

GUS-QS8A-02-4642-FA Features

• Precision Thin Film Technology: Offers superior stability, low noise, and high accuracy compared to thick-film alternatives.
• Isolated Resistors (ISOL): Each of the 8 resistors operates independently, ideal for signal isolation or multi-channel circuits.
• Robust Power Handling: 0.75W total dissipation (0.1W per resistor) with derating up to 125°C.
• Compact QSOP Package: 4.9mm x 6.02mm footprint and 1.63mm seated height optimize board space.
• Wide Voltage Rating: Supports up to 100V, suitable for industrial and instrumentation applications.
• Non-Automotive (PPAP No): Optimized for commercial and industrial use where PPAP compliance is not required.

GUS-QS8A-02-4642-FA Applications

• Precision Analog Circuits: Voltage dividers, DAC/ADC reference networks, and sensor signal conditioning.
• Medical Electronics: Patient monitoring equipment requiring stable, low-drift resistance.
• Test & Measurement: Calibration tools and high-accuracy instrumentation.
• Industrial Control Systems: Isolated signal paths in PLCs and motor drives.
• Communications: RF matching networks and filter circuits where consistency is critical.
