GQ8A032490FT Description

The GQ8A032490FT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 249Ω resistance value with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Encased in a ceramic QSOP package, it offers superior thermal stability and durability. The 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits. Its 16-pin gull-wing SMD termination ensures reliable surface-mount assembly, while the ±0.1mm height/length tolerances guarantee consistent PCB integration.

GQ8A032490FT Features

• Precision Thin Film Technology: Delivers high accuracy (±1%) and low TCR (±25ppm/°C) for stable performance.
• Robust Ceramic QSOP Package: Enhances thermal management and mechanical strength in harsh environments.
• Isolated Resistor Network (ISOL): Each resistor operates independently, ideal for signal isolation.
• High Power Handling: 0.75W total (0.1W per resistor) supports power-sensitive designs.
• Surface-Mount Gull Wing Terminals: Ensures secure PCB mounting with a 0.64mm pitch for high-density layouts.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, suitable for industrial and automotive-grade applications (though not PPAP/Automotive certified).
