GUS-QS8A-03-8661-FF Description

The GUS-QS8A-03-8661-FF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 8.66KΩ resistance value with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a compact 16-pin QSOP package with gull-wing SMD termination, it offers a 0.75W (3/4W) total power rating (0.1W per resistor) and a maximum voltage rating of 100V. Its rectangular, surface-mount design (4.9mm x 6.02mm x 1.47mm) makes it ideal for space-constrained PCB layouts.

GUS-QS8A-03-8661-FF Features

• Precision Thin Film Technology: Delivers high accuracy (±1%) and low TCR (±25ppm/°C) for stable operation.
• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk in sensitive circuits.
• Robust Power Handling: Supports 0.75W total power dissipation (0.1W per resistor) at 125°C maximum operating temperature.
• Compact QSOP Package: Space-saving 16-pin gull-wing SMD with 0.64mm terminal pitch for high-density designs.
• Wide Voltage Range: 100V maximum rating suits industrial and instrumentation applications.
• Non-Automotive, Non-PPAP: Optimized for general-purpose and commercial electronics.

GUS-QS8A-03-8661-FF Applications

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor conditioning.
• Signal Isolation: Buffering and impedance matching in communication systems.
• Medical & Test Equipment: High-reliability instrumentation requiring low drift.
• Industrial Controls: PLCs, motor drives, and power management modules.
