GQ8A013240FAT Description

The GQ8A013240FAT from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. Encased in a ceramic QSOP package, it offers a 324Ω resistance per resistor with a tight 1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. The 16-pin gull-wing SMD configuration and 0.64mm terminal pitch facilitate compact PCB layouts, while the 0.75W (3/4W) total power rating (0.1W per resistor) supports robust operation in demanding circuits. Its isolated (ISOL) circuit design enhances signal integrity, making it ideal for noise-sensitive environments.

GQ8A013240FAT Features

• Precision Thin Film Technology: Delivers superior accuracy (±1%) and low TCR (±100ppm/°C) for stable resistance over temperature fluctuations.
• Ceramic QSOP Package: Combines high thermal conductivity with mechanical durability, suited for harsh environments.
• High Power Density: 0.75W total rating (0.1W per resistor) in a compact 4.9mm × 6.02mm × 1.47mm footprint.
• Isolated Design (ISOL): Eliminates crosstalk between resistors, critical for analog signal conditioning and feedback circuits.
• Wide Voltage Rating: Supports up to 100V, accommodating industrial and automotive-grade applications (though not PPAP-certified).
• Gull-Wing Termination: Ensures reliable surface-mount soldering with ±0.1mm height tolerance for consistent PCB assembly.

GQ8A013240FAT Applications

• Analog Signal Processing: Precision voltage dividers, DAC/ADC reference networks, and sensor conditioning circuits.
