GUS-QS8A-02-4020-FB Description

The GUS-QS8A-02-4020-FB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 402Ω resistance value with a tight 1% tolerance and a low ±50ppm/°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, it offers a 0.75W (3/4W) total power rating and 0.1W (1/10W) per resistor, making it suitable for space-constrained designs requiring reliable power dissipation. The gull-wing termination and 0.64mm terminal pitch facilitate easy surface-mount assembly, while its 100V maximum voltage rating enhances durability in demanding circuits.

GUS-QS8A-02-4020-FB Features

• Precision Thin Film Technology: Delivers high accuracy (±1%) and low TCR (±50ppm/°C) for stable signal conditioning.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), ideal for high-density PCB layouts.
• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk in multi-channel systems.
• Robust Power Handling: 0.75W total rating with derated performance up to 125°C.
• Gull-Wing SMD Termination: Ensures reliable solder joints and compatibility with automated assembly processes.
• Non-Automotive (PPAP No): Optimized for industrial, telecom, and instrumentation applications.
