GQ8A022942FT Description

The GQ8A022942FT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 8-resistor ISOL (isolated) configuration device offers a 29.4KΩ resistance per resistor with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a 16-pin QSOP ceramic package, it features gull-wing SMD termination for reliable surface-mount assembly. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it is engineered for precision analog and digital circuits requiring isolation and minimal drift.

GQ8A022942FT Features

• High Accuracy: 1% tolerance and ±50ppm/°C TCR for consistent performance.
• Robust Construction: Ceramic case with gull-wing leads for mechanical durability and thermal stability.
• Compact Design: 4.9mm × 6.02mm × 1.47mm QSOP package saves PCB space.
• Isolated Resistors: Independent 29.4KΩ resistors (ISOL design) for flexible circuit integration.
• Wide Operating Range: Derated power up to 125°C, suitable for industrial environments.
• Surface-Mount Ready: 0.64mm terminal pitch for automated assembly compatibility.

GQ8A022942FT Applications

Ideal for precision applications such as:

• Signal conditioning in data acquisition systems.
• Voltage dividers and reference circuits in test equipment.
• Isolation networks in medical devices and industrial controls.
• Feedback networks for op-amps and ADCs/DACs.
• Automotive sensors (though not PPAP/AEC-Q200 qualified).

Conclusion of GQ8A022942FT

The GQ8A022942FT excels in high-reliability, space-constrained designs requiring stable resistance values under thermal stress. Its thin-film technology, ceramic encapsulation, and isolated resistor array make it superior to thicker-film or polymer-based networks in precision-critical roles. While not RoHS-compliant or automotive-grade, it is a cost-effective choice for industrial, medical, and instrumentation applications demanding long-term accuracy and minimal drift.
