GUS-QS8A-03-1130-FF Description

The GUS-QS8A-03-1130-FF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP package features 8 isolated resistors, each with a 113 Ω resistance value and a tight 1% tolerance, ensuring consistent performance in demanding circuits. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it operates reliably across a wide temperature range of 70°C to 125°C, derated for optimal stability. The ±25ppm/°C temperature coefficient minimizes resistance drift, making it ideal for precision analog and digital systems.

GUS-QS8A-03-1130-FF Features

• Thin-Film Technology: Delivers superior accuracy, low noise, and stability compared to thick-film alternatives.
• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk in multi-channel applications.
• High Power Handling: 0.75W total dissipation with 100V maximum voltage rating, suitable for power-sensitive designs.
• Compact QSOP Package: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) footprint with 0.64mm pitch gull-wing leads, enabling high-density PCB layouts.
• Robust Construction: -55°C to +125°C operating range and RoHS non-compliant (suitable for legacy or specialized applications).
