GQ8A032740FT Description

The GQ8A032740FT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low temperature coefficients. This 8-resistor isolated network features a 274Ω resistance per element with a tight 1% tolerance and a ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide operating temperature range of -70°C to +125°C. Housed in a 16-pin QSOP ceramic package, it offers excellent thermal stability and durability in demanding environments. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this component is ideal for circuits requiring isolation and precision.

GQ8A032740FT Features

• Thin-film technology: Delivers superior accuracy, low noise, and stability compared to thick-film alternatives.
• Ceramic case: Enhances thermal performance and mechanical robustness.
• Gull-wing termination: Ensures reliable surface-mount (SMD) compatibility for automated assembly.
• Isolated circuit design (ISOL): Provides independent resistors, reducing crosstalk in sensitive applications.
• Compact dimensions: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth) for space-constrained designs.
• Wide temperature range: Operates reliably from -70°C to +125°C, making it suitable for industrial and automotive-adjacent applications (though not PPAP/Automotive certified).

GQ8A032740FT Applications

This resistor network excels in:

• Precision analog circuits: Voltage dividers, feedback networks, and sensor interfaces where low TCR (±25ppm/°C) is critical.
• Signal conditioning: Isolation buffers in data acquisition systems or medical instrumentation.
• Power management: Load balancing in DC-DC converters or power supplies due to its 0.75W collective power handling.
• Industrial controls: PLCs, motor drives, and test equipment requiring stable performance under thermal stress.
• Telecommunications: RF modules and filtering circuits benefiting from its low parasitic effects.
