GQ8A023481JFT Description

The GQ8A023481JFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and robust thermal performance. This 8-resistor isolated network features a 3.48KΩ resistance per resistor with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring reliable operation across a wide temperature range of 70°C to 125°C. Housed in a 16-pin QSOP ceramic package, it offers a compact 4.9mm x 6.02mm footprint with a 1.47mm profile, making it ideal for space-constrained designs. The gull-wing termination facilitates easy surface-mount assembly, while the 100V maximum voltage rating and 0.75W total power dissipation (0.1W per resistor) enhance durability in demanding circuits.

GQ8A023481JFT Features

• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk in multi-channel systems.
• Ceramic QSOP Case: Provides superior thermal conductivity and mechanical stability vs. plastic alternatives.
• Thin-Film Technology: Delivers low noise and high precision, critical for analog signal conditioning.
• Wide Operating Range: Rated for -55°C to +125°C, suitable for industrial and automotive environments (though non-PPAP).
• High Power Density: 0.75W total rating in a miniature package outperforms comparable arrays.
• Strict Tolerances: ±0.1mm length/height tolerances ensure consistent PCB placement.

GQ8A023481JFT Applications

This resistor network excels in:

• Signal Isolation Circuits: Precision dividers or feedback networks in op-amp stages.
• Medical Equipment: Patient monitoring systems requiring stable, noise-free resistance paths.
• Test & Measurement: Calibration modules where temperature stability (±50ppm/°C) is critical.
• Industrial Controls: PLCs or motor drivers benefiting from its 100V isolation rating.
• Aerospace Avionics: Non-RoHS compliant version suits legacy systems needing ceramic robustness.

Conclusion of GQ8A023481JFT

The GQ8A023481JFT stands out for its isolated thin-film design, ceramic-enhanced reliability, and high power-to-size ratio. While not automotive-grade (no PPAP), its wide temperature range and low TCR make it a top choice for precision electronics. Engineers should consider this model for applications demanding miniaturization without compromising performance, particularly where thermal management and signal integrity are priorities.
