GQ8A031051JFT Description

The GQ8A031051JFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low thermal drift. This 8-resistor isolated network features a 1.05KΩ resistance per resistor with a 5% tolerance and a ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range of 70°C to 125°C. Housed in a 16-pin QSOP ceramic package, it offers a 0.75W (3/4W) total power rating and 0.1W per resistor, making it suitable for demanding circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its 100V maximum voltage rating enhances durability in high-voltage environments.

GQ8A031051JFT Features

• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk in sensitive applications.
• Ceramic Case & Thin-Film Technology: Delivers superior thermal stability and low noise compared to thick-film alternatives.
• Precision Tolerance: ±5% resistance tolerance and ±25ppm/°C TCR ensure consistent performance.
• Robust Construction: Withstands high temperatures (up to 125°C) and derated power conditions.
• Compact QSOP Package: 4.9mm x 6.02mm footprint and 1.47mm height save board space in dense layouts.
