GQ8A024750JT

GQ8A024750JT Description

The GQ8A024750JT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low thermal drift. This 8-resistor isolated network features a 475Ω resistance per element with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range of 70°C to 125°C. Housed in a 16-pin QSOP ceramic package, it offers excellent thermal stability and durability, making it suitable for demanding environments. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this component is engineered for efficiency and longevity in surface-mount applications.

GQ8A024750JT Features

• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk and improving signal integrity.
• Ceramic Case & Thin Film Technology: Delivers superior thermal performance and long-term stability compared to thick-film alternatives.
• Gull Wing Termination: Ensures secure surface-mount attachment with a 0.64mm terminal pitch for high-density PCB layouts.
• Precision Specifications: ±0.1mm length/height tolerances and ±0.2mm depth tolerance for consistent manufacturing compatibility.
• Wide Operating Range: Functions reliably from -55°C to +125°C (derated above 70°C), ideal for industrial and automotive-grade designs (though not PPAP/automotive-certified).

GQ8A024750JT Applications

This resistor network excels in:

• Signal Conditioning & Voltage Division: Precision analog circuits, sensor interfaces, and feedback networks.
• Industrial Control Systems: PLCs, motor drives, and power supplies requiring stable resistance under thermal stress.
• Test & Measurement Equipment: Calibration tools and instrumentation where low TCR (±50ppm/°C) minimizes drift.
• Medical Electronics: Isolated circuits in diagnostic devices, though RoHS non-compliance may limit use in certain regions.

Conclusion of GQ8A024750JT

The GQ8A024750JT stands out for its ceramic-packaged isolation, thin-film accuracy, and robust power handling, making it a top choice for engineers prioritizing reliability in harsh conditions. While not automotive-qualified, its QSOP footprint and gull-wing terminals simplify integration into space-constrained designs. Ideal for industrial, medical, and precision analog applications, this network balances performance with cost-effectiveness in medium-volume production (packaged in tubes). For non-RoHS-restricted projects, it offers a compelling alternative to higher-tolerance, more expensive options.
