GQCA011240GFT Description

The GQCA011240GFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. This 24-pin QSOP package features 12 isolated resistors, each with a 124Ω resistance value and a tight 2% tolerance, ensuring consistent performance in demanding circuits. The ceramic case style and gull-wing termination provide robust mechanical stability and reliable surface-mount compatibility. With a ±100ppm/°C temperature coefficient and a 1W total power rating (0.1W per resistor), this network excels in environments with operating temperatures up to 125°C. Packaged in a tube for automated assembly, it combines precision and durability for industrial and telecom applications.

GQCA011240GFT Features

• High Precision: 2% tolerance and ±100ppm/°C TCR ensure minimal drift under thermal stress.
• Robust Construction: Ceramic substrate and gull-wing terminals enhance mechanical and thermal reliability.
• Isolated Design: 12 independent resistors (ISOL circuit designator) prevent cross-talk in sensitive circuits.
• Wide Operating Range: Derated power capability from 70°C to 125°C, with a 100V maximum voltage rating.
• Compact Footprint: 8.66mm × 6.02mm × 1.47mm QSOP package (±0.1mm dimensional tolerance) optimizes PCB space.
• Thin-Film Technology: Delivers superior stability and low noise compared to thick-film alternatives.

GQCA011240GFT Applications

Ideal for precision analog circuits, signal conditioning, and voltage division in:

• Industrial Control Systems: Sensor interfaces, PLCs, and instrumentation requiring stable resistance.
• Telecommunications: RF modules and filtering circuits where low TCR is critical.
• Medical Electronics: Patient monitoring devices demanding high reliability.
• Automotive (Non-Automotive Rated): Prototyping or non-safety-critical subsystems.

Conclusion of GQCA011240GFT

The GQCA011240GFT stands out for its isolated thin-film resistors, tight tolerances, and ceramic-enhanced durability, making it a superior choice for precision applications. While not PPAP or automotive-qualified, its 125°C rating and low TCR suit harsh environments. Engineers will value its balance of performance, compactness, and cost-effectiveness in high-reliability designs.
