GQ8A011200GFT Description

The GQ8A011200GFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 120Ω resistance value per resistor with a tight 2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a ceramic QSOP package, it offers 0.75W (3/4W) total power rating (0.1W per resistor) and a maximum voltage rating of 100V. Its 16-pin gull-wing SMD termination and surface-mount design make it ideal for compact PCB layouts. The non-automotive, non-PPAP compliant part is supplied in tubes, catering to prototyping and low-to-medium volume production.

GQ8A011200GFT Features

• Precision Thin Film Technology: Delivers superior accuracy (±2%) and low TCR (±100ppm/°C) for stable operation in varying environments.
• Robust Ceramic QSOP Package: Enhances thermal management and mechanical durability, with dimensions of 4.9mm (L) × 6.02mm (D) × 1.47mm (H) and tight tolerances (±0.1mm height/length, ±0.2mm depth).
• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk in multi-channel systems.
• High Power Density: 0.75W total dissipation (0.1W per resistor) at 125°C maximum operating temperature, outperforming standard arrays in power handling.
• Gull-Wing Termination: Ensures reliable solder joints for surface-mount assembly, with a 0.64mm terminal pitch for high-density layouts.
