GUS-QS8A-03-4420-DB Description

The GUS-QS8A-03-4420-DB from TT Electronics/IRC is a high-precision 8-resistor thin-film network designed for demanding surface-mount applications. Encased in a 16-pin QSOP package with gull-wing terminations, it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) and robust performance in industrial environments. Each resistor features a 442Ω resistance with a tight 0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The isolated (ISOL) circuit design allows independent resistor operation, while the 0.75W total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for high-reliability circuits.

GUS-QS8A-03-4420-DB Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Compact QSOP Package: Ideal for space-constrained PCBs, with a 0.64mm terminal pitch for high-density layouts.
• Isolated Resistor Network: Each of the 8 resistors operates independently, enhancing design flexibility.
• Extended Temperature Range: Reliable performance from -70°C to +125°C, even at derated power (70°C to 125°C).
• Robust Power Handling: 0.75W total dissipation (3/4W) with 0.1W per resistor, exceeding typical network ratings.
• Strict Tolerances: ±0.1mm height/length and ±0.2mm depth tolerances ensure consistent mounting.

GUS-QS8A-03-4420-DB Applications
