GQ8A021741FT Description

The GQ8A021741FT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring tight tolerances and stable operation. This 8-resistor isolated network features a 1.74KΩ resistance value per resistor with a 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range of 70°C to 125°C. Housed in a 16-pin QSOP ceramic package, it offers a 0.75W (3/4W) total power rating and 0.1W per resistor, making it suitable for demanding circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its 100V maximum voltage rating enhances durability in high-voltage environments.

GQ8A021741FT Features

• Precision Thin Film Technology: Delivers ±50ppm/°C thermal stability and 1% tolerance for critical analog/digital circuits.
• Robust Ceramic Package: Ensures high thermal conductivity and mechanical strength, ideal for harsh environments.
• Isolated Network (ISOL): Each resistor operates independently, reducing crosstalk in multi-channel systems.
• Compact QSOP-16 Form Factor: 4.9mm x 6.02mm footprint with 1.47mm profile saves board space in dense layouts.
• Wide Operating Range: -70°C to +125°C with derated power, suitable for industrial and automotive-grade designs (though not PPAP/automotive-certified).
• High Power Handling: 0.75W total dissipation outperforms standard networks in power-sensitive applications.

GQ8A021741FT Applications

• Signal Conditioning: Precision voltage dividers and feedback networks in op-amp circuits.
• Medical Electronics: Isolated measurement systems requiring low drift and high accuracy.
• Test & Measurement Equipment: Calibration circuits and sensor interfaces demanding stable resistance values.
• Industrial Controls: PLCs and motor drives where ceramic packaging resists vibration and thermal stress.
• Communications Infrastructure: RF matching networks and filtering due to low parasitic effects.

Conclusion of GQ8A021741FT

The GQ8A021741FT stands out for its combination of precision, power handling, and compactness, making it a superior choice over generic resistor arrays. Its ceramic QSOP package and isolated thin-film design cater to high-reliability applications, though designers should note its non-compliance with EU RoHS. Ideal for engineers prioritizing thermal stability and space efficiency, this network excels in mission-critical electronics where performance cannot be compromised.
