GUS-QS8A-03-1650-FD Description

The GUS-QS8A-03-1650-FD from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 165Ω resistance value per resistor 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 (QSOP-16) package, it offers a 0.75W (3/4W) total power rating and 0.1W (1/10W) per resistor, making it suitable for power-sensitive designs. The gull-wing termination and 0.64mm terminal pitch facilitate easy surface-mount (SMD) assembly, while its 4.9mm x 6.02mm footprint and 1.47mm profile optimize space efficiency.

GUS-QS8A-03-1650-FD Features

• Precision Thin Film Technology: Delivers high accuracy (±1%) and low TCR (±25ppm/°C) for stable operation in varying thermal conditions.
• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk in multi-channel systems.
• Robust Power Handling: Supports 0.75W total dissipation (0.1W per resistor) at 125°C maximum operating temperature.
• Compact QSOP Package: Ideal for high-density PCB layouts with a 1.63mm seated height and 100V maximum voltage rating.
• Industrial-Grade Reliability: Non-automotive (PPAP: No) but suited for industrial, telecom, and instrumentation applications.
• Tube Packaging: Ensures safe handling and storage during assembly.
