GQ8A011911GFT Description

The GQ8A011911GFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 1.91KΩ resistance value 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 16-pin QSOP ceramic package, it offers excellent thermal stability and durability. The 0.75W (3/4W) total power rating and 0.1W per resistor make it suitable for demanding circuits, while its 100V maximum voltage rating ensures reliability in high-voltage environments. The gull-wing termination and surface-mount design facilitate easy PCB integration.

GQ8A011911GFT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy for sensitive analog/digital circuits.
• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk in multi-channel systems.
• Robust Ceramic Package: Enhances thermal dissipation and mechanical strength compared to plastic alternatives.
• Wide Operating Range: Functions reliably from -55°C to 125°C (derated power up to 125°C).
• Compact QSOP Form Factor: 4.9mm x 6.02mm footprint with a 1.63mm profile, ideal for space-constrained designs.
• Stable Performance: ±0.1mm to ±0.2mm dimensional tolerances ensure consistent mounting alignment.
