GQ8A021621FFT

GQ8A021621FFT Description

The GQ8A021621FFT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring stable performance and tight tolerances. This 8-resistor isolated network features a 1.62KΩ resistance value per resistor with a 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. Encased in a ceramic QSOP package, it offers excellent thermal stability and durability, with a maximum operating temperature of 125°C. The 16-pin gull-wing SMD termination facilitates reliable surface mounting, while the 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating make it suitable for compact, power-sensitive designs.

GQ8A021621FFT Features

• Precision Thin Film Technology: Delivers high accuracy (±1%) and low TCR (±50ppm/°C) for stable performance.
• Robust Ceramic Package: Enhances thermal management and mechanical strength in harsh environments.
• Isolated Circuit Design (ISOL): Each resistor operates independently, ideal for multi-channel applications.
• Compact QSOP-16 Form Factor: Saves board space with a 4.9mm × 6.02mm footprint and 1.47mm profile.
• Wide Voltage Rating: Supports up to 100V, suitable for industrial and automotive-grade circuits (though not PPAP/automotive-certified).
• Surface-Mount Gull Wing Terminals: Ensures secure PCB attachment with a 0.64mm pitch for high-density layouts.

GQ8A021621FFT Applications

This resistor network excels in precision analog and digital circuits, including:

• Signal Conditioning: Voltage dividers, feedback networks, and sensor interfaces in test/measurement equipment.
