GUS-QS8A-03-64R9-GD Description

The GUS-QS8A-03-64R9-GD is a high-performance 8-resistor thin film network from TT Electronics/IRC, designed for precision applications requiring stable resistance values and low thermal drift. Encased in a 16-pin QSOP package with gull-wing terminations, this surface-mount device offers a 64.9Ω resistance per element with a tight 2% tolerance and an ultra-low ±25ppm/°C temperature coefficient. Its isolated (ISOL) circuit design ensures independent resistor functionality, making it ideal for signal conditioning and impedance matching. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it operates reliably across a -70°C to +125°C derated temperature range.

GUS-QS8A-03-64R9-GD Features

• Precision Thin Film Technology: Delivers stable performance with minimal noise and drift.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), enabling high-density PCB layouts.
• High Power Handling: 0.75W total dissipation (0.1W per resistor) outperforms similar networks in its class.
• Wide Temperature Range: Operates from -70°C to +125°C, suitable for industrial and automotive-adjacent environments (though not PPAP/automotive-certified).
• Isolated Resistors: Independent elements allow flexible circuit design without crosstalk.
• RoHS Non-Compliant: Note: Contains leaded terminations for enhanced solderability in non-RoHS applications.
