GQ8A021470GFT Description

The GQ8A021470GFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 147 Ohm resistance value with a tight 2% 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 ceramic QSOP package, it offers a 0.75W (3/4W) total power rating (0.1W per resistor) and a maximum voltage rating of 100V. The 16-pin gull-wing SMD termination ensures reliable surface-mount compatibility, while the rectangular ceramic case provides excellent thermal and mechanical stability.

GQ8A021470GFT Features

• Precision Thin Film Technology: Delivers high accuracy (±2%) and low TCR (±50ppm/°C) for stable operation in demanding environments.
• Robust Ceramic Package: Enhances thermal dissipation and durability compared to plastic alternatives.
• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk in multi-channel systems.
• High Power Handling: 0.75W total rating (0.1W per resistor) supports power-sensitive applications.
• Surface-Mount Gull Wing Terminals: Ensures secure PCB attachment with a 0.64mm pitch for high-density layouts.
• Wide Temperature Range: Operates reliably from 70°C to 125°C, making it suitable for industrial and automotive-adjacent uses (though not PPAP/Automotive certified).

GQ8A021470GFT Applications

This resistor network is ideal for:

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor interfaces requiring tight tolerance.
• Signal Conditioning: Isolation and impedance matching in communication systems.
• Industrial Control Systems: PLCs, motor drives, and power supplies where thermal stability is critical.
• Test & Measurement Equipment: Calibration circuits and reference networks due to low TCR.
• Medical Electronics: Isolated signal paths in diagnostic devices (note: EU RoHS non-compliant).

Conclusion of GQ8A021470GFT

The GQ8A021470GFT stands out for its ceramic-encased thin-film precision, making it a robust choice for high-reliability applications. Its isolated design, high power rating, and wide temperature range offer superior performance over plastic-packaged networks. While not RoHS-compliant or automotive-grade, it excels in industrial, medical, and instrumentation roles where accuracy and thermal resilience are paramount. The QSOP gull-wing package ensures compatibility with automated assembly, streamlining production for high-volume OEMs.
