GUS-QS8A-02-2871-FF Description

The GUS-QS8A-02-2871-FF from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. With a 2.87KΩ resistance value and a tight 1% tolerance, this QSOP-packaged device offers excellent stability and accuracy. Its isolated (ISOL) circuit design ensures independent resistor functionality, making it ideal for complex signal conditioning and voltage division tasks. The network operates over a wide temperature range (-70°C to +125°C) with a low ±50ppm/°C temperature coefficient, ensuring reliable performance in demanding environments. Rated for 0.75W (3/4W) total power and 0.1W per resistor, it supports robust power handling while maintaining compact dimensions (4.9mm x 6.02mm x 1.47mm).

GUS-QS8A-02-2871-FF Features

• Precision Thin Film Technology: Delivers high accuracy (±1%) and low TCR (±50ppm/°C) for stable performance.
• Isolated Resistor Network (ISOL): Each of the 8 resistors operates independently, enhancing design flexibility.
• Compact QSOP-16 Package: Space-saving surface-mount design with 0.64mm terminal pitch for high-density PCB layouts.
• Wide Operating Range: Functions reliably from -70°C to +125°C, suitable for industrial and automotive-grade applications (though not PPAP/automotive certified).
• High Voltage Rating: Supports up to 100V, making it versatile for analog and digital circuits.
• Gull Wing Termination: Ensures secure soldering and mechanical stability in SMD assemblies.
