GQ8A027872DBT Description

The GQ8A027872DBT from TT Electronics/IRC is a high-precision, surface-mount thin-film resistor network designed for demanding isolation and signal conditioning applications. This 16-pin QSOP (Quarter-Small Outline Package) device features 8 isolated resistors, each with a 78.7KΩ resistance value and a tight ±0.5% tolerance, ensuring exceptional accuracy in circuit design. Encased in a robust ceramic package, it offers superior thermal stability and mechanical durability. With a ±50ppm/°C temperature coefficient, it maintains consistent performance across a wide operating temperature range of -70°C to +125°C. The 0.75W (3/4W) total power rating and 100V maximum voltage rating make it suitable for high-reliability applications.

GQ8A027872DBT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog circuits.
• Isolated Resistor Network (ISOL): Each of the 8 resistors is electrically isolated, enabling flexible circuit configurations.
• Ceramic QSOP Package: Enhances thermal dissipation and withstands harsh environments.
• Gull Wing Termination: Ensures reliable surface-mount soldering with a 0.64mm terminal pitch for compact PCB layouts.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, with derated power up to 125°C.
• High Power Handling: 0.1W per resistor (0.75W total) for power-sensitive designs.

GQ8A027872DBT Applications

This resistor network is ideal for:

• Industrial Automation: Precision voltage dividers, sensor conditioning, and isolation circuits in PLCs.
