GQ8A0390R9DT Description

The GQ8A0390R9DT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding isolation and signal conditioning applications. Housed in a 16-pin QSOP ceramic package, it features a 90.9Ω resistance per resistor with an ultra-tight ±0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide -70°C to +125°C operating range. The 0.75W (3/4W) total power rating and 100V maximum voltage rating make it suitable for robust circuit designs. Its gull-wing termination and surface-mount (SMD) form factor (4.9mm x 6.02mm x 1.47mm) enable compact PCB layouts.

GQ8A0390R9DT Features

• Precision Thin Film Technology: Delivers superior accuracy (±0.5%) and low TCR (±25ppm/°C) for stable performance in temperature-variable environments.
• High Power Handling: 0.1W per resistor (0.75W total) outperforms standard networks in power dissipation.
• Isolation-Centric Design: "ISOL" circuit designator ensures minimal crosstalk, ideal for analog/digital isolation.
• Ceramic QSOP Package: Enhances thermal management and mechanical durability vs. plastic alternatives.
• Automation-Friendly: Tube packaging and 0.64mm pitch gull-wing leads streamline pick-and-place assembly.
