GQ8A034422GFT Description

The GQ8A034422GFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low temperature coefficients. This 8-resistor isolated network features a 44.2K Ohm resistance per resistor with a tight 2% tolerance and an ultra-low ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range of 70 to 125°C. Housed in a 16-pin QSOP ceramic package, it offers excellent thermal stability and durability, making it suitable for demanding environments. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating provide robust power handling.

GQ8A034422GFT Features

• Precision Thin Film Technology: Delivers high accuracy (±2%) and low TCR (±25ppm/°C) for stable performance.
• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk in sensitive circuits.
• Ceramic QSOP Package: Enhances thermal management and mechanical strength.
• Wide Operating Range: Rated for -55°C to +125°C, with derated power up to 125°C.
• Surface-Mount Gull Wing Terminals: Ensures secure PCB mounting with a 0.64mm pitch for high-density layouts.
• High Voltage Rating: Supports up to 100V, ideal for industrial and automotive applications (non-AECQ).
• Non-RoHS Compliant: Suitable for legacy or specialized systems requiring leaded components.
