GQ8A013090DT Description

The GQ8A013090DT 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 309Ω resistance per element with an ultra-tight ±0.5% tolerance and ±100ppm/°C temperature coefficient, ensuring stability across a -70°C to +125°C operating range. The 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for power-sensitive circuits. Its gull-wing termination and surface-mount design (4.9mm × 6.02mm × 1.47mm) enable compact PCB integration.

GQ8A013090DT Features

• Precision Thin Film Technology: Delivers low noise and high stability for critical analog/digital interfaces.
• Isolated Circuit Design (ISOL): Ideal for applications requiring electrical separation between channels.
• Ceramic QSOP Package: Enhances thermal performance and mechanical durability vs. plastic alternatives.
• Wide Temperature Range: Operates reliably from -70°C to +125°C with derated power at elevated temperatures.
