GQ0A027320FT

GQ0A027320FT Description

The GQ0A027320FT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP package integrates 10 isolated resistors, each with a 732Ω resistance value, 1% tolerance, and a ±50ppm/°C temperature coefficient. The ceramic case ensures excellent thermal stability, while the gull-wing termination facilitates reliable surface-mount assembly. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network operates reliably across a wide temperature range of 70°C to 125°C. Packaged in a tube, it meets industrial standards but is not PPAP or automotive qualified.

GQ0A027320FT Features

• Precision Performance: Thin-film technology delivers low TCR (±50ppm/°C) and tight tolerance (1%), ideal for precision circuits.
• Robust Construction: Ceramic substrate enhances thermal dissipation and mechanical durability.
• Isolated Design: 10 resistors in isolated configuration (ISOL) minimize crosstalk, suitable for high-impedance or noise-sensitive applications.
• Space-Efficient: Compact QSOP package (8.66mm x 6.02mm x 1.47mm) with 0.64mm pitch optimizes PCB real estate.
• Industrial-Grade: Operates up to 125°C with derated power, though non-RoHS compliance may restrict use in certain regions.

GQ0A027320FT Applications

• Signal Isolation: Perfect for ADC/DAC reference dividers, sensor interfaces, and medical instrumentation requiring stable, isolated resistances.
• Communication Systems: Used in RF matching networks and impedance control due to low parasitic effects.
• Test & Measurement: Calibration circuits and precision voltage dividers benefit from its low TCR and tolerance.
• Industrial Controls: Suitable for PLC I/O modules where isolation and reliability are critical.

Conclusion of GQ0A027320FT

The GQ0A027320FT excels in precision, isolation, and thermal performance, making it a standout choice for high-accuracy analog designs. While its non-automotive and non-RoHS status limits some applications, its ceramic construction, thin-film technology, and isolated network offer superior stability over standard thick-film arrays. Engineers seeking repeatable performance in harsh environments will find this resistor network indispensable for critical signal-path applications.
