GUS-QS8A-02-3900-DB Description

The GUS-QS8A-02-3900-DB from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. Housed in a compact 16-pin QSOP package with gull-wing terminations, it offers a 390Ω resistance per element with an ultra-tight ±0.5% tolerance and a low ±50ppm/°C temperature coefficient. Rated for 0.75W (3/4W) total power and 0.1W per resistor, it operates reliably across a -55°C to +125°C range (derated to 70°C–125°C). Its 100V maximum voltage rating and isolated (ISOL) circuit design make it ideal for precision analog and digital circuits requiring stable performance under thermal stress.

GUS-QS8A-02-3900-DB Features

• Thin Film Technology: Ensures low noise, high stability, and superior accuracy compared to thick-film alternatives.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), saving PCB space in dense layouts.
• High Power Handling: 0.75W total dissipation (0.1W per resistor) supports energy-intensive applications.
• Precision Tolerance: ±0.5% tolerance and ±50ppm/°C TCR minimize drift in precision voltage dividers or feedback networks.
• Robust Construction: Gull-wing leads provide reliable solder joints for automated assembly processes.
• Wide Temperature Range: Operates from -55°C to +125°C, suitable for industrial and automotive environments (though not PPAP/automotive-certified).

GUS-QS8A-02-3900-DB Applications

• Analog Signal Conditioning: Precision dividers, gain networks in op-amp circuits.
• Medical Electronics: Patient monitoring systems requiring stable resistance under thermal cycling.
• Test & Measurement Equipment: Calibration circuits, sensor interfaces.
• Industrial Controls: PLCs, motor drives where space and reliability are critical.
• Communications Hardware: RF matching networks, filter tuning.
