GQ8A034220GFT Description

The GQ8A034220GFT 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 422Ω resistance per resistor with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The isolated (ISOL) circuit design allows independent resistor functionality, while the 0.1W power rating per resistor (0.75W total) and 100V maximum voltage rating make it suitable for demanding environments. Its 16-pin gull-wing SMD termination ensures reliable surface-mount assembly, and the ceramic construction enhances thermal and mechanical durability.

GQ8A034220GFT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive circuits.
• Isolated Resistor Network: Each of the 8 resistors operates independently, ideal for multi-channel designs.
• Robust Ceramic Package: Withstands high temperatures (up to 125°C) and mechanical stress.
• Compact QSOP-16 Footprint: 4.9mm x 6.02mm x 1.47mm dimensions with ±0.1mm length/height tolerances for space-constrained PCBs.
• Low TCR (±25ppm/°C): Minimizes resistance drift in varying thermal conditions.
• Gull-Wing Termination: Ensures reliable solder joints for automated SMD processes.
