GUS-QS8A-03-3160-JA Description

The GUS-QS8A-03-3160-JA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding electronic circuits. This 8-resistor isolated network features a 316Ω resistance value per resistor with a 5% tolerance and an ultra-stable ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range of -70°C to +125°C. Housed in a compact 16-pin QSOP (QSOP-16) package, it offers a 0.75W (3/4W) total power rating and 0.1W per resistor, making it ideal for space-constrained designs requiring consistent power dissipation. The gull-wing termination ensures secure surface-mount (SMD) assembly, while its 100V maximum voltage rating enhances durability in high-voltage environments.

GUS-QS8A-03-3160-JA Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Isolated Network (ISOL): Each resistor operates independently, reducing crosstalk in multi-channel systems.
• Robust Power Handling: 0.75W total power (0.1W per resistor) with derating up to 125°C.
• Compact QSOP Package: 4.9mm × 6.02mm × 1.47mm dimensions with ±0.1mm length/height tolerances for high-density PCB layouts.
• Wide Operating Range: Performs reliably from -70°C to +125°C, suitable for industrial and automotive-grade applications (though not PPAP/automotive certified).
• Gull-Wing Termination: Ensures strong solder joints and mechanical stability in SMT processes.

GUS-QS8A-03-3160-JA Applications

This resistor network excels in:

• Signal Conditioning: Precision voltage dividers, feedback networks in op-amp circuits.
