GQ8A031180FT Description

The GQ8A031180FT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 8-resistor isolated network features a 118Ω resistance value with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable 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. The device is rated for 0.1W per resistor (0.75W total power dissipation) and supports a maximum voltage of 100V, making it suitable for precision analog and digital circuits. Its gull-wing termination and surface-mount design facilitate easy PCB integration.

GQ8A031180FT Features

• High Precision: 1% tolerance and ±25ppm/°C TCR ensure minimal drift in critical applications.
• Robust Construction: Ceramic case enhances thermal performance and mechanical strength.
• Isolated Design: Each resistor is electrically isolated (ISOL), ideal for multi-channel signal conditioning.
• Compact Footprint: 4.9mm × 6.02mm × 1.47mm dimensions with a 0.64mm terminal pitch save board space.
• Wide Operating Range: Functions reliably from -55°C to +125°C (derated power above 70°C).
• Surface-Mount Ready: Gull-wing terminals simplify automated assembly processes.

GQ8A031180FT Applications

This resistor network excels in:

• Precision voltage dividers and sensor signal conditioning in industrial controls.
• Analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) requiring matched resistances.
• Medical instrumentation where stability and accuracy are critical.
• Telecommunications equipment for impedance matching and termination.
• Automotive subsystems (non-AECQ qualified) in non-safety-critical roles.

Conclusion of GQ8A031180FT

The GQ8A031180FT stands out for its combination of precision, isolation, and compactness, making it a superior choice for high-reliability circuits.
