GQ8A031401FAT Description

The GQ8A031401FAT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a ceramic QSOP package, it offers 1.4KΩ resistance per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of -70°C to +125°C. The device features 16 gull-wing terminals for reliable surface-mount (SMD) assembly, with a compact footprint of 4.9mm (L) × 6.02mm (D) × 1.47mm (H). Rated for 0.75W total power dissipation (0.1W per resistor) and 100V maximum voltage, it is ideal for high-density circuits requiring isolation and precision.

GQ8A031401FAT Features

• Isolated Resistor Network: Each of the 8 resistors is electrically isolated (designated ISOL), reducing crosstalk in sensitive circuits.
• Ceramic QSOP Package: Provides superior thermal performance and mechanical robustness compared to plastic alternatives.
• Thin-Film Technology: Delivers low noise, high accuracy, and long-term reliability.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, with derated power up to 125°C.
• Precision Specifications: 1% tolerance and ±25ppm/°C TCR ensure consistent performance in demanding environments.
• Gull-Wing Termination: Facilitates automated PCB assembly and strong solder joints.

GQ8A031401FAT Applications

This resistor network excels in:

• Industrial Control Systems: Signal conditioning, voltage division, and feedback networks in PLCs and sensors.
• Medical Electronics: Precision analog circuits in diagnostic equipment where stability is critical.
• Telecommunications: Isolation and impedance matching in RF and baseband circuits.
• Automotive (Non-Automotive Rated): Engine control units (ECUs) and infotainment systems, though not PPAP-certified.
• Test & Measurement Equipment: Calibration and reference circuits requiring low drift.

Conclusion of GQ8A031401FAT

The GQ8A031401FAT stands out for its ceramic-encased isolation, thin-film precision, and compact QSOP footprint, making it a superior choice for high-reliability applications. While not RoHS-compliant or automotive-grade, its wide temperature range, low TCR, and high power rating make it ideal for industrial, medical, and telecom designs where accuracy and durability are paramount. Its gull-wing SMD termination further ensures ease of integration into modern PCB assemblies.
