GUS-QS8A-01-49R9-JF Description

The GUS-QS8A-01-49R9-JF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 49.9Ω resistance value with a 5% tolerance and a ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of -70°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 PCB designs. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this non-automotive, non-PPAP compliant component is RoHS non-compliant and supplied in tube packaging.

GUS-QS8A-01-49R9-JF Features

• Thin-Film Technology: Delivers superior accuracy, low noise, and excellent thermal stability compared to thick-film alternatives.
• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk and improving signal integrity.
• High Power Density: 0.75W total power dissipation in a compact QSOP package, ideal for high-density layouts.
• Wide Temperature Range: Reliable operation from -70°C to +125°C, with derated power handling at elevated temperatures.
• Gull-Wing SMD Termination: Ensures robust mechanical attachment and compatibility with automated assembly processes.
• Low TCR (±100ppm/°C): Minimizes resistance drift under thermal stress, critical for precision analog circuits.
