GUS-QS8A-03-3160-FF Description

The GUS-QS8A-03-3160-FF from TT Electronics/IRC is a high-performance 8-resistor isolated thin-film network designed for precision applications. Encased in a compact 16-pin QSOP package with gull-wing SMD termination, this resistor array offers a 316Ω resistance per element with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide -55°C to +125°C operating range. Its 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits requiring reliable power dissipation. The isolated (ISOL) circuit design allows independent resistor operation, enhancing flexibility in circuit design.

GUS-QS8A-03-3160-FF Features

• Thin-Film Technology: Delivers superior accuracy, low noise, and long-term stability compared to thick-film alternatives.
• High Power Density: 0.75W total power in a miniature 4.9mm × 6.02mm × 1.47mm footprint, ideal for space-constrained PCBs.
