GUS-QS8A-03-3010-GA Description

The GUS-QS8A-03-3010-GA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 8-resistor isolated network features a 301Ω resistance value per resistor with a tight 2% tolerance and an ultra-stable ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide operating temperature range of -55°C to +125°C. Housed in a 16-pin QSOP package with gull-wing SMD termination, it offers a compact footprint (4.9mm length × 6.02mm depth × 1.47mm height) and a 0.64mm terminal pitch, making it ideal for space-constrained designs. With a derated power handling of 0.1W per resistor (0.75W total) and a 100V maximum voltage rating, this network balances power efficiency with signal integrity.

GUS-QS8A-03-3010-GA Features

• Precision Thin-Film Technology: Delivers low noise, high stability, and excellent TCR performance (±25ppm/°C).
• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk in sensitive analog/digital circuits.
• Robust Power Handling: Supports 0.75W total power dissipation (derated to 70–125°C) for demanding applications.
• Compact QSOP Package: Space-saving 16-pin gull-wing SMD profile with a 1.63mm seated height suits high-density PCBs.
