GUS-QS8A-03-1870-JF Description

The GUS-QS8A-03-1870-JF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 187Ω resistance value per resistor with a 5% tolerance and a ±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) 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 surface-mount (SMD) design facilitate easy PCB integration, while its 100V maximum voltage rating enhances durability in demanding circuits.

GUS-QS8A-03-1870-JF Features

• Thin-Film Technology: Delivers superior accuracy, low noise, and excellent stability compared to thick-film alternatives.
• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk and improving signal integrity.
• Compact & Robust: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with a 0.64mm terminal pitch, ideal for high-density layouts.
• Wide Temperature Range: Operates reliably from -55°C to +125°C (derated power up to 125°C).
• High Power Handling: 0.75W total power rating and 100V max voltage support industrial-grade applications.
• Gull-Wing SMD Termination: Ensures secure soldering and mechanical stability in automated assembly processes.
