GUS-QS8A-01-44R2-GG Description

The GUS-QS8A-01-44R2-GG from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 44.2 Ω resistance value with a tight 2% tolerance and a low ±100 ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of -70°C to +125°C. Packaged in a 16-pin QSOP with gull-wing SMD termination, it offers a compact footprint (4.9 mm × 6.02 mm × 1.47 mm) ideal for space-constrained PCB designs. The 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating make it suitable for moderate power dissipation requirements.

GUS-QS8A-01-44R2-GG Features

• Precision Thin Film Technology: Delivers superior accuracy (±2%) and low TCR (±100 ppm/°C) for stable operation in varying thermal conditions.
• Isolated Network (ISOL): Each resistor is electrically isolated, providing flexibility in circuit design.
• Robust Construction: QSOP package with gull-wing leads ensures reliable surface-mount assembly and mechanical durability.
• Wide Voltage Rating: Supports up to 100V, making it suitable for both low and medium-voltage applications.
• High-Temperature Capability: Rated for 125°C maximum operating temperature, ideal for industrial and automotive-adjacent environments (though not PPAP/Automotive certified).
• Tight Dimensional Tolerances: ±0.1 mm (L/W) and ±0.2 mm (D) for consistent PCB placement.
