GQCA031782GGT Description

The GQCA031782GGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and tight tolerances. This 24-pin QSOP (Quarter Small Outline Package) device integrates 12 isolated resistors, each rated at 17.8KΩ with a 2% tolerance and a low ±25ppm/°C temperature coefficient. Encased in a ceramic package, it offers superior thermal stability and durability, making it suitable for demanding environments. The gull-wing termination ensures reliable surface-mount (SMD) assembly, while the 1W total power rating (0.1W per resistor) supports moderate power dissipation.

GQCA031782GGT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±2%) for signal conditioning and analog circuits.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, ensuring reliability in elevated temperatures.
• Isolated Resistors (ISOL): Each of the 12 resistors is electrically isolated, providing design flexibility in multi-channel systems.
• Robust Ceramic Case: Enhances thermal conductivity and mechanical strength compared to plastic alternatives.
• Compact QSOP Package: 8.66mm × 6.02mm footprint with a 1.47mm profile, ideal for space-constrained PCBs.
• High Voltage Rating: Supports up to 100V, suitable for industrial and instrumentation applications.

GQCA031782GGT Applications

This resistor network excels in:

• Analog Signal Processing: Precision voltage dividers, DAC/ADC interfaces, and feedback networks.
• Industrial Controls: PLCs, sensor conditioning, and power management circuits requiring stable resistance.
• Test & Measurement Equipment: Calibration circuits and reference networks due to low TCR (±25ppm/°C).
• Medical Electronics: Isolated signal paths in diagnostic devices where accuracy is critical.
• Automotive (Non-Automotive Rated): Prototyping or non-safety-critical systems, though not PPAP-certified.
