GQ8A039090FAT Description

The GQ8A039090FAT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 909Ω resistance value with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a ceramic QSOP package, it offers excellent thermal stability and durability. 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 moderate power applications.

GQ8A039090FAT Features

• Precision Thin Film Technology: Delivers high accuracy (±1%) and low TCR (±25ppm/°C) for stable performance.
• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk in sensitive circuits.
• Robust Ceramic Package: Enhances thermal management and mechanical strength.
• Surface-Mount Gull Wing Terminals: Ensures secure PCB attachment with a 0.64mm pitch for high-density layouts.
• Wide Operating Range: Rated for -55°C to +125°C, with derated power up to 125°C.
• Compact Dimensions: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm L/H, ±0.2mm D).

GQ8A039090FAT Applications

This resistor network is ideal for:

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor interfaces.
• Industrial Control Systems: Signal conditioning and isolation in harsh environments.
• Medical Electronics: High-reliability instrumentation requiring stable resistance values.
• Telecommunications: Impedance matching and filtering in RF/mixed-signal PCBs.
• Automotive (Non-Automotive Rated): Prototyping or non-safety-critical circuits.
