GUS-QS8A-01-31R6-JC Description

The GUS-QS8A-01-31R6-JC from TT Electronics/IRC is a high-performance 8-resistor isolated network designed for precision applications in demanding environments. This thin-film resistor array features a 31.6Ω resistance value per resistor with a 5% tolerance and a ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of -70°C to +125°C. Housed in a compact 16-pin QSOP package with gull-wing SMD termination, it offers a 0.75W (3/4W) total power rating (0.1W per resistor) and a maximum voltage rating of 100V. Its isolated circuit design (ISOL) ensures minimal crosstalk between resistors, making it ideal for signal conditioning and precision analog circuits.

GUS-QS8A-01-31R6-JC Features

• High-Density Integration: 8 resistors in a 4.9mm x 6.02mm footprint with 0.64mm terminal pitch, saving PCB space.
• Robust Thin-Film Technology: Delivers low noise, high stability, and tight TCR performance (±100ppm/°C).
• Wide Operating Range: Rated for -70°C to +125°C, suitable for industrial and automotive-adjacent applications (though not PPAP/Automotive certified).
• Isolated Design (ISOL): Eliminates mutual interference, critical for precision voltage dividers and feedback networks.
• Surface-Mount Gull Wing Terminals: Ensures reliable solder joints and compatibility with automated assembly processes.
• Non-RoHS Compliant: May be preferred for legacy or high-reliability systems requiring specific material properties.

GUS-QS8A-01-31R6-JC Applications

• Signal Conditioning: Ideal for ADC/DAC reference networks, sensor interfaces, and amplifier feedback loops.
