GQCA021541GFT Description

The GQCA021541GFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 24-pin QSOP device features 12 isolated resistors, each with a 1.54KΩ resistance and a tight 2% tolerance, ensuring consistent performance in demanding circuits. Encased in a ceramic package, it offers superior thermal stability and durability, with a maximum operating temperature of 125°C and a ±50ppm/°C temperature coefficient. The gull-wing termination and surface-mount design facilitate easy integration into compact PCB layouts, while the 0.1W power rating per resistor (1W total) ensures reliable operation under load.

GQCA021541GFT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Isolated Resistor Configuration (ISOL): Each of the 12 resistors operates independently, ideal for multi-channel isolation.
• Robust Ceramic Case: Enhances thermal dissipation and mechanical strength in harsh environments.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, suited for industrial and automotive-grade applications (though not PPAP or Automotive certified).
• Compact QSOP Package: 8.66mm × 6.02mm × 1.47mm dimensions with ±0.1mm length/height tolerances enable high-density designs.
• 100V Maximum Voltage Rating: Supports moderate-voltage applications like signal conditioning and voltage dividers.

GQCA021541GFT Applications

This resistor network excels in:

• Analog Signal Processing: Precision voltage division in data acquisition systems.
• Industrial Control Systems: Isolated feedback networks in PLCs and motor drives.
• Test & Measurement Equipment: Stable reference resistors for calibration circuits.
• Medical Electronics: Low-drift configurations in diagnostic devices.
