GQCA021101GFT Description

The GQCA021101GFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 24-pin QSOP (Quarter Small Outline Package) device features 12 isolated resistors, each with a resistance value of 1.1K Ohm and a tight tolerance of ±2%. Encased in a durable ceramic package, it offers excellent thermal stability with a low temperature coefficient of ±50ppm/°C and operates across a wide temperature range of -70°C to +125°C. The gull-wing termination ensures secure surface mounting (SMD), while the 0.1W power rating per resistor (1W total) and 100V maximum voltage rating make it suitable for demanding circuits.

GQCA021101GFT Features

• High Precision: Thin-film technology ensures low tolerance (±2%) and minimal drift (±50ppm/°C).
• Robust Construction: Ceramic case enhances thermal performance and mechanical durability.
• Isolated Design: 12 independent resistors (ISOL circuit designator) prevent crosstalk in sensitive applications.
• Compact & Reliable: QSOP package (8.66mm × 6.02mm × 1.47mm) with ±0.1mm dimensional tolerances for high-density PCB layouts.
• Wide Operating Range: Derated power up to 125°C, ideal for industrial and automotive-adjacent environments (though not PPAP/Automotive certified).
• Surface-Mount Ready: Gull-wing terminals with 0.64mm pitch for automated assembly.

GQCA021101GFT Applications

This resistor network excels in precision analog and digital circuits, including:

• Signal Conditioning: Isolation and impedance matching in sensor interfaces or data acquisition systems.
