GQCA035112GFT Description

The GQCA035112GFT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 24-pin QSOP package integrates 12 isolated resistors, each with a 51.1KΩ resistance, 2% tolerance, and a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The ceramic case style and gull-wing termination provide robust mechanical and thermal stability, making it suitable for surface-mount (SMD) applications. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network excels in precision analog and mixed-signal circuits.

GQCA035112GFT Features

• High Precision: Thin-film technology delivers ±2% tolerance and low TCR (±25ppm/°C) for stable operation.
• Robust Construction: Ceramic substrate ensures durability and excellent thermal dissipation.
• Isolated Design: 12 independent resistors (ISOL circuit designator) prevent crosstalk in sensitive applications.
• Compact & Reliable: QSOP package (8.66mm x 6.02mm x 1.47mm) with ±0.1mm dimensional tolerances for high-density PCB layouts.
• Wide Operating Range: Rated for -55°C to +125°C, derated up to 125°C, ideal for industrial environments.
• Automotive-Grade Alternatives: While this model is not PPAP or automotive-qualified, its performance rivals AEC-Q200-compliant parts in non-automotive settings.

GQCA035112GFT Applications

• Signal Isolation: Ideal for ADC/DAC reference dividers, sensor conditioning, and op-amp feedback networks.
• Medical & Industrial Electronics: Precision voltage division in patient monitoring systems or PLC analog I/O modules.
• Test & Measurement Equipment: Low-noise resistor networks for calibration circuits and precision instrumentation.
• Communications: Impedance matching and termination in RF front-end circuits or high-speed data converters.
• Power Management: Voltage sensing in DC-DC converters or battery management systems (BMS).
