GQ8A028062FFT Description

The GQ8A028062FFT from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. Housed in a 16-pin QSOP ceramic package, it offers an 80.6K Ohm resistance with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. The device features gull-wing terminations for reliable surface-mount (SMD) assembly and is supplied in a tube packaging for ease of handling. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it is engineered for demanding circuit environments.

GQ8A028062FFT Features

• Precision Thin Film Technology: Delivers high accuracy (±1%) and low TCR (±50ppm/°C) for stable performance in temperature-varying conditions.
• Robust Ceramic QSOP Package: Enhances thermal management and durability, suitable for industrial and automotive-grade applications (though not PPAP or Automotive certified).
• Isolated Resistor Network (ISOL): Each of the 8 resistors is electrically isolated, providing design flexibility in signal conditioning and voltage division circuits.
• Space-Efficient Design: Compact dimensions (4.9mm x 6.02mm x 1.47mm) with a 0.64mm terminal pitch enable high-density PCB layouts.
• High Voltage Tolerance: Supports up to 100V, making it ideal for analog and mixed-signal systems requiring voltage buffering or attenuation.

GQ8A028062FFT Applications

This resistor network excels in:

• Precision Analog Circuits: Such as op-amp feedback networks, DAC/ADC interfaces, and sensor signal conditioning.
• Industrial Control Systems: Where stable resistance values are critical under thermal stress (e.g., PLCs, motor drives).
• Test & Measurement Equipment: For calibration and reference voltage generation due to its low drift and high accuracy.
• Medical Electronics: In isolated signal paths where reliability and consistency are paramount.

Conclusion of GQ8A028062FFT

The GQ8A028062FFT stands out for its combination of precision, power handling, and compact form factor, making it a superior choice over generic thick-film networks. Its ceramic construction and thin film technology ensure long-term reliability in harsh environments, while the isolated design simplifies circuit integration. Though not RoHS-compliant, it remains a robust solution for engineers prioritizing performance in high-accuracy, high-density applications.
