GQ0A035491FFT

GQ0A035491FFT Description

The GQ0A035491FFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP package features 10 isolated resistors, each with a 5.49KΩ resistance and a tight 1% tolerance, ensuring consistent performance in critical circuits. The device operates over a wide temperature range of 70°C to 125°C with a ±25ppm/°C temperature coefficient, making it suitable for environments with thermal fluctuations. Its ceramic case and gull-wing termination provide robust mechanical stability and reliable surface-mount compatibility. With a maximum voltage rating of 100V and a total power dissipation of 1W (0.1W per resistor), this network balances power handling and precision.

GQ0A035491FFT Features

• High Precision: 1% tolerance and ±25ppm/°C TCR ensure minimal drift in demanding conditions.
• Robust Construction: Ceramic substrate enhances thermal stability and durability.
• Space-Efficient: QSOP package (8.66mm x 6.02mm x 1.47mm) optimizes board space in dense layouts.
• Isolated Design: 10 independent resistors (ISOL circuit) prevent cross-talk in sensitive analog/digital systems.
• Surface-Mount Ready: Gull-wing leads with 0.64mm pitch facilitate automated assembly.
• Wide Operating Range: -55°C to +125°C (derated above 70°C) for industrial and automotive-grade reliability (though not PPAP/automotive certified).
