GQCA012741GFT Description

The GQCA012741GFT 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 2.74KΩ resistance value and a tight 2% tolerance, ensuring consistent performance in critical circuits. The ceramic case style and gull-wing termination enable robust surface-mount (SMD) integration, while the ±100ppm/°C temperature coefficient guarantees minimal resistance drift across a wide operating range of -70°C to +125°C. With a maximum voltage rating of 100V and a power rating of 1W (0.1W per resistor), this network is ideal for high-density PCB designs demanding durability and precision.

GQCA012741GFT Features

• Thin-Film Technology: Delivers superior stability, low noise, and high accuracy compared to thick-film alternatives.
• Isolated Resistors (ISOL): 12 independent resistors prevent crosstalk, making it suitable for signal isolation and precision voltage division.
• Ceramic QSOP Package: Enhances thermal performance and mechanical strength in harsh environments.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, with derated power up to 125°C.
• Gull-Wing Termination: Ensures secure soldering and compatibility with automated SMD assembly processes.
• Low TCR (±100ppm/°C): Minimizes resistance variation under thermal stress, critical for analog and sensor circuits.

GQCA012741GFT Applications

This resistor network excels in:

• Industrial Control Systems: Signal conditioning, feedback loops, and isolation in PLCs and motor drives.
• Medical Electronics: Precision instrumentation where stable resistance and low drift are paramount.
• Telecommunications: Impedance matching and filtering in RF modules and base stations.
• Automotive (Non-Automotive Rated): Sensor interfaces and ECU peripherals (though not PPAP/automotive certified).
• Test & Measurement Equipment: Calibration circuits and reference voltage networks.
