GQ8A035490FAT Description

The GQ8A035490FAT from TT Electronics/IRC is a high-precision 8-resistor thin-film network designed for demanding isolation and signal conditioning applications. Housed in a 16-pin QSOP ceramic package, it features a 549Ω resistance value per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this component is engineered for reliability in surface-mount (SMD) designs. Its gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while the ceramic case enhances thermal and mechanical durability.

GQ8A035490FAT Features

• Precision Thin-Film Technology: Delivers low noise and high stability for sensitive circuits.
• Isolation-Centric Design (ISOL): Ideal for applications requiring electrical separation between channels.
• Compact QSOP Package (4.9mm × 6.02mm × 1.47mm): Saves board space without compromising performance.
• Wide Operating Temperature (-70°C to +125°C): Suitable for industrial and automotive-adjacent environments (though not PPAP/Automotive certified).
• Robust Ceramic Construction: Superior heat dissipation and mechanical strength vs. plastic-bodied alternatives.
• Non-RoHS Compliant: May be preferred for legacy or high-reliability systems requiring leaded soldering.
