GQ8A021270GDT Description

The GQ8A021270GDT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 127Ω resistance value with a tight 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Encased in a ceramic QSOP package, it offers excellent thermal stability and durability. The 16-pin gull-wing SMD termination facilitates reliable surface-mount assembly, while the 0.75W (3/4W) total power rating (0.1W per resistor) supports robust operation in demanding circuits.

GQ8A021270GDT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±50ppm/°C) for sensitive analog/digital circuits.
• Isolated Circuit Design (ISOL): Each resistor operates independently, ideal for multi-channel isolation.
• High Power Handling: 0.75W total (0.1W per resistor) at 125°C, derated for extended reliability.
• Compact & Robust: Ceramic QSOP package (4.9mm x 6.02mm x 1.47mm) with ±0.1mm dimensional tolerances for tight PCB layouts.
• Wide Voltage Range: Supports up to 100V, suitable for industrial and instrumentation use.
• Non-Automotive Grade: Optimized for general-purpose applications where PPAP compliance is not required.
