GQ0A011742FAT

GQ0A011742FAT Description

The GQ0A011742FAT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP package features 10 isolated resistors, each with a 17.4KΩ resistance, 1% tolerance, and a ±100ppm/°C temperature coefficient. Encased in a ceramic substrate, it offers superior thermal stability and durability, with a maximum operating temperature of 125°C. The 1W total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits. Its gull-wing termination and surface-mount design ensure reliable PCB integration, while the QSOP package (8.66mm x 6.02mm x 1.47mm) optimizes space efficiency.

GQ0A011742FAT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Isolated Resistors (ISOL): Each of the 10 resistors operates independently, reducing crosstalk in multi-channel systems.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, ideal for industrial environments.
• Robust Ceramic Case: Enhances thermal dissipation and mechanical strength compared to polymer-based networks.
• 1% Tolerance & ±100ppm/°C TCR: Ensures consistent performance in precision voltage dividers or feedback networks.
• Compact QSOP Package: Saves board space while supporting high-density layouts.
