GUS-QS8A-03-9530-JB Description

The GUS-QS8A-03-9530-JB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance and low thermal drift. This 8-resistor isolated network features a 953Ω resistance per element with a 5% tolerance and a ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range (70°C to 125°C). Housed in a 16-pin QSOP package, it offers a compact 4.9mm × 6.02mm footprint with a 1.47mm profile, making it ideal for space-constrained surface-mount (SMD) designs. The gull-wing termination ensures secure PCB mounting, while the 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating provide robust handling of distributed loads.

GUS-QS8A-03-9530-JB Features

• Thin-Film Technology: Delivers superior stability, low noise, and precision compared to thick-film alternatives.
• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk in sensitive analog/digital circuits.
• High-Temperature Resilience: Rated for 125°C maximum operating temperature, suitable for industrial and automotive-adjacent environments (though not PPAP/automotive-certified).
• Compact QSOP Package: 0.64mm terminal pitch and 1.63mm seated height enable high-density PCB layouts.
• 100V Maximum Voltage Rating: Supports moderate-voltage applications like signal conditioning and voltage dividers.
• Tube Packaging: Protects components during handling and assembly.

GUS-QS8A-03-9530-JB Applications

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor interfaces benefit from low TCR (±25ppm/°C).
